For each of the questions you have listed, there is opposite viewpoints of some (questionable) legitimacy:
White supremacists would argue that it is multiculturalists who seek the abolition of the white race through introduction of millions of high birth rate other demographics into white countries.
Pro-conversion therapy anti gay people would argue they are saving the individuals from mental problems, social difficulties, and other negative side effects of what they believe is a consciously modifiable behaviour.
"Racists" and "sexists" would argue that being aware of mean average behavioural differences in different demographics is not a negative thing.
However invalid these arguments may, or may not, be, it is not our job to attempt to generalise our expertise and judge anyone who holds a differing view.
Simple statistics says that there is at least one or two major issues which you are extremely passionate about, but simply mistaken. Same for me, same for anyone else.
That does not matter. As long as my opinions do not measurably affect my behaviour within a specific community, then it is not relevant. People should be judged by their individual actions within a given 'organism'/community/company/etc, not their viewpoints on tangentially related subjects shared with others in other communities.
Your logic is exactly what led to the exclusion of gays, blacks, communists, non christians, and other groups, in the 1950s and before.
You risk going so far in the other direction that you become exactly what you opposed.
