Just like there are many reasons why the climate is getting warmer, not just humans.

Fun fact, what you're arguing is actually one of the reasons Charlie was murdered.

He notoriously said that the Civil Rights Act was a mistake. He specifically referred to Title VII which states even a neutral policy can be racism if it produces disparate impact[1] in practice. That is, if a neutral policy results in fewer black people being hired, that's evidence of racism. Charlie disagreed with that.

It's fun to see leftists argue the same when it comes to discrimination against right wing or centrist academics.
