Hey RedRanger let's start a proper discussion topic so hopefully the mods won't close your thread:
Diversity and (tribal) hatred are actually two highly correlated variables, and the correlation is most likely causal - so the more diverse a society becomes, the more and more that society's constituent tribes hate each other and the more likely tribal conflict becomes.
I've posted this most recent gem of a scientific paper published in 2015, "The Nature of Conflict," on this topic at least twice here before but I will post it again. The beauty of this paper is that the authors themselves are 'diverse' fellows - Cemal Arbatli is a Turkish scientist and Quamrul Ashraf is a Bangladeshi scientist.
Man this is why I love scientific folk (oh and I don't consider social science a la sociology mumbo jumbo as science)!
Whatever their ethnic background - most of them have a penchant for the pursuit of truth wherever it leads, unlike SJWs and their religious fanatic methodological brethren whose modus operandi is to crush the world into the image of their personal Truth.
Anyways enough of the rambling, I'll quote some salient passages that are not mathematical but I encourage you to read the paper for yourself:

"Civil conflicts in the post World War II era have resulted in more than 16 million casualties across
the globe, surpassing the loss of human life associated with interstate wars. Regions plagued by civil
conflicts have experienced significant human casualties, substantial loss of productive resources, and
considerable reduction in productivity, investment, and trade flows. Further, more than 20% of all
nations experienced at least 10 years of civil conflict during the 1960–2006 time period. While the
proportion of countries with active conflicts declined from 52 at its peak in the early 1990s, more
than 30 countries were still experiencing one or more civil conflicts in 2008."
"This research advances the hypothesis that the emergence, prevalence, and recurrence of
civil conflicts across the globe reflect the long shadow of prehistory. The analysis establishes that the
genetic diversity of contemporary national populations, as determined predominantly in the course
of the exodus of humans from Africa tens of thousands of years ago, has contributed to the frequency,
incidence, and onset of both civil and ethnic conflicts over the last half century, accounting for the
potentially confounding influence of a wide variety of factors, including traditional group-based
measures of diversity such as ethnic and linguistic fractionalization and polarization."
"Genetic diversity may contribute to the emergence of civil conflicts through three direct
channels. First, as argued by Ashraf and Galor (2013a), genetic diversity has had an adverse
effect on trust and cooperation among members of society, and it can thereby reduce the sociocultural threshold for the onset of a conflict. Second, to the extent that diversity in preferences over
public goods and political outcomes reflect diversity in genetic traits, social conflicts could be more
prevalent in more diverse societies. Third, genetic diversity and its manifestation in heterogeneity
in cognitive and physical traits may have contributed to inequality and, thus, to socio-political
instability and the propensity for civil conflicts."
"The empirical analysis establishes that genetically diverse countries have had a significantly
higher propensity for civil and ethnic conflicts, accounting for the potentially confounding effects
of ethnic fractionalization and polarization, institutional characteristics, income, population size,
and several geographical factors that have received much attention in the empirical literature on
cross-country comparative development and civil conflict. Furthermore, it is shown that the results
are qualitatively insensitive to the data sources and the underlying codings for conflicts. Moreover,
the analysis establishes that the reduced-form impact of genetic diversity on conflicts may, indeed,
partly operate through two mediating channels, namely interpersonal trust and ethnolinguistic
fragmentation."
"Population geneticists measure the extent of diversity in genetic material across individuals
within a given population (e.g., an ethnic group) using an index called expected heterozygosity.
Like most other measures of diversity, this index may be interpreted simply as the probability that
two individuals, selected at random from the relevant population, are genetically different from
one another with respect to a given spectrum of traits. Specifically, the expected heterozygosity
measure for a given population is constructed by geneticists using sample data on allelic frequencies.
Given allelic frequencies for a particular gene or DNA locus, a gene-specific heterozygosity statistic
may be computed (i.e., the probability that two randomly selected individuals differ with respect
to the gene in question), which when averaged over multiple genes or DNA loci yields the overall
expected heterozygosity for the relevant population."
"This research establishes that the emergence, prevalence, and recurrence of civil conflicts in the
modern era reflect the long shadow of prehistory. Exploiting variations across national populations,
it establishes that genetic diversity, as determined predominantly during the “out of Africa”
migration of humans to the rest of the world tens of thousands of years ago, has contributed
significantly to the incidence, onset, and frequency of both ethnic and overall civil conflicts in the
last half century, accounting for a large set of potential correlates of civil conflict. Importantly,
the positive reduced-form causal effect of genetic diversity on civil conflict survives a wide range of
robustness checks."
"The influence of genetic diversity on civil conflict arguably reflects the adverse effect of
genetic diversity on interpersonal trust and cooperation, the potential impact of diversity on
income inequality, the potential association between diversity and divergence in preferences for
public goods and redistributive policies, and the contribution of genetic diversity to the degree
of fractionalization and polarization across ethnic and linguistic groups in the population. The
analysis demonstrates that the reduced-form impact of genetic diversity on conflicts may, indeed,
partly operate through interpersonal trust and ethnolinguistic fragmentation."
So my friends, those platitudes about diversity being a strength are childish hopes at best.
The truth is that diversity is a recipe for civil war and has been one of the primary causes of war based death in the post WWII era.
