You can't have diversity without exclusion. In order to create a space that has some vibe different from the lowest common denominator of general public, you need to exclude everyone except some groups. Case in point: when I'm organizing a house party, I avoid inviting people who would ruin the vibe, even if they're otherwise fine people.
As much as some people hate to admit this, the recent cultural shift overcorrected towards feminism and non-white races. I'm not saying that Andrew Tate will become mainstream, but I guess in near future it will become acceptable again to shamelessly be a white straight man.
That's totally acceptable. It's being an unrepentant asshole that people have troubles with.
