Straight white guys are on the top of the "privilege hierarchy", but unfortunately, they don't understand that.

Something that oppressed minorities tend to have that straight white guys don't is a sense of community and solidarity. We have "our people", basically, and at least to an extent that can give a sense of belonging.

Those guys don't have that. Now, they also don't face any oppression whatsoever and will generally get baseline preferential treatment, but they aren't aware of that, they just see what others have and they don't. Then they see liberal media constantly praising minorities and they constantly hear how terrible cishet white men are, maybe they even see a person of color become a quota hire or something.

These people feel lost. They think "if white privilege is real, why do i feel like shit?"

And then some clown like Peterson comes and is like "It is me, Professor Smartman, and I am here to tell you that indeed, you guys are the most oppressed, you can read all about it in my book."

Say what you will about Contrapoints, but her way of reaching out to these kinds of people played a big part in growing online leftist spaces. As dumb as it is, they're a demographic that matters if you want to accomplish pretty much anything.
