To be honest, I think most people aren't at the extreme but the most extreme voices are amplified so loudly that it seems like there are many more of them than there actually are. Unfortunately, corporations and politicians are placating these amplified voices instead of the majority of reasonable people - much to their own detriment and the detriment of of society at large.
It's pretty common to discriminate based off race and sex. Public institutions due it as a matter of policy in the name of social justice. I'm not sure how it could be more mainstream.
