White supremacist thinking became nearly extinct as society moved beyond the idea of race and encouraged race neutrality.

The reality is white racism, which was a specific and cultural mindset, inspired a reactionary black identity movement in the 60's and 70's.

Race essentialism on the left manifested in direct and open racial discrimination and stereotyping, focused negatively and exclusively on white people.

Is it any surprise a segment of white people responded by adopting white supremacist ideology?

Racism begets racism.

I remember the Pulse terrorist attack vividly.
I remember walking into work and seeing the quiet, concerned look on my coworker's faces unsure of what to say or do.
I remember my friends calling me to ask if I was ok and suddenly feeling like the LGBT community was one.

The issue conservatives have is not what the left is doing to themselves, but what they're imposing onto us.

Progressive policies force compliance, they don't unite or persuade or offer.

They use the full force of government to make you do what they believe is best.
