But is the refusal of gay marriage equivalent to blacks being refused the right to vote?
They're both about discrimination so they're in the same category but based on different aspects. Sexual orientation and racism. Black people probably suffer more since they're judged for who
they are, while (in you question) gay people are 'only' denied the right to get legally married.
(*I know gay people are judged as well but my answer is purely based on your question).
Personally I don't get being gay, I don't understand it but I don't think they're harming anyone,
so they have my support. Marriage with really huge age for example bother me, but not gay marriages.
I also believe that racism will never fade and almost every person is somewhat judgemental.
They endure more than we can imagine but of course the racism-card is played easily.
I try my best to look at everyone the same no matter what their sexual orientation or skin color is.
