Plain old racism/xenophobia and sexism was very common and still is to some extent, though it is not as socially acceptable as it used to be. So I find it odd to only consider anti-white bias you encountered while ignoring any discrimination in the other direction. I strongly doubt it does not exist.
There is certainly stuff under the diversity banner, especially when done primarily with PR/image concerns that reasonable people can object to. But there are also real issues with discrimination, and efforts to address that are a good idea in my opinion.
To highlight an inconsistency in a system isn't ignoring the system's other problems. If anything, it compliments a broader perspective rather than a narrow one. I don't think a lot of people here are suggesting that there aren't other forms of racism and sexism taking place.
"In other words, people who are racist against white people just have an anti-white bias. People that are racist against black people are actual racists."
This is such an insane statement I don't even know how to reply on a site like HN. Do you personally believe this, or are you just pasting what the (recently modified, I'm sure) current definition of "racism" is?
I've talked with enough "woke" activists to know that they are not oblivious to this glaring contradiction. While most don't say it outright, since whites are perceived to be privileged and the main offenders of racism, racism against them is to be accepted during this "transition" period to equality.
