First of all, white supremacy is still a thing. It exists as part of the alt-right. With that out of the way...it's a pretty general post you've made so I'll just cover it generally.
Recently there's been a massive increase in terms of how reactive the world is to particular issues regarding social values and issues. As you've stated in your post, there are more and more people coming out as being victimized by some particular problem or persons, and there has been an increased presence and significance of feminists and pro-equality movements. A mistake a lot of people make is marginalizing or trivializing the issues a lot of these people, e.g. females and those of the LGBTQI population, face. People like to chalk up their feelings and issues as stemming from personal or political 'agenda', which I think is really sad and short-sighted. People forget how privileged they are to simply be born a male, and stay a male for their whole life for example. People in the LGBTQI community still face a lot of problems, because of these very people who just trivialize or reject their issues and disregard them entirely. It's this distinct lack of acceptance that poses such a large problem for LGBTQI peoples. The recent poll on the legalization of SSM here in Australia came out with a yes vote as the majority decision, which is a big thing. And just to speak on the "ideology that there are more than 2 genders" part of your post; it's not simply an ideology, its a fact. Around the world, there are millions, probably billions of people, who express a gender that is outside of the "traditional" male/female assignment. And the reason for most of their problems is that their cries for help are dismissed by people who reject them and don't accept them. Its created a very toxic environment for LGBTQI peoples. Its always been an uphill battle for that community, but its one that will hopefully end in a more peaceful and united community in which everybody is accepted and welcomed.
Feminism, just like LGBTQI movements, is very important. Women still face problems of their own, that are disregarded and rejected by others. Again, it comes down to the privilege and preconceptions that have been built up over a long, long time. Feminism by definition is the desire for equality between men and women, so if you're against that, you're part of the problem really. What a lot of people direct their disdain towards is 'extreme feminism', which at that point isn't technically feminism anymore, and has, unfortunately, become the expectation or preconception of feminism. The recent torrent of sexual assault (or general misconduct) allegations is a perfect example of female issues being dismissed, with total lack of consideration and insight into what problem women actually face in their daily life compared to that of males. People practice purposeful ignorance of the real problem and prefer to focus on the time between the incident and actually reporting it, and trivial shit like that. They misconstrue the problems of women and are part of the grave problem that faces women currently in society.
Black people can be racist, just as much as everyone else can be racist. Whoever thinks that any one group of people are incapable of or immune to racism probably don't actually know the definition of racism, or they're just idiots.
Edit: sorry for the wallie, but its covered my thoughts succinctly @_@
