You contradict yourself. You imagine a school where everyone looks the same but thinks "different", and yet by your own definition that school doesn't have any women, blacks, gays, etc. How would that work? Do you imagine an academy of straight white men, some of which serve as delegates for the types of thought that emerge from groups that aren't allowed to attend?
> You imagine a school where everyone looks the same
The author of that comment does not want everybody to look the same, it was just a rhetorical device - the problem is not that people don't look the same, but that looks is everything that is considered. The opposite of "caring only about physical diversity" is not "demanding physical uniformity", it's "demanding diversity not only in genetic traits but also in other aspects". I am old enough to remember when the need for diversity was explained as "we need people of different background with different ways of thinking, because that would lead to greater intellectual outcomes as individual biases would be compensated and cancelled out". Now it's "we need people of different genetic background because if you don't agree with it than shut up, racist!". Somehow the old one was way more intellectually satisfying than the new one.
in my hypothetical, I don't care what they look like, they could all be asian lesbians. There are conservative asian lesbians. There are liberal asian lesbians. Poor. Rich. Urban. Rural. From America. From Europe. ad infinitum. As long there is a good mix of backgrounds and ideologies. I will very much take that environment over a rainbow coalition will make attempts to ruin someone who dares disagree with the hivemind.
Regarding tolerance - you do not see conservatives trying to no-platform liberals, but I could get you 100 examples of college liberals trying to no-platform conservatives. Who exactly are the tolerant ones?
Did you see what happened to Bret Weinstein at Evergreen College? He is an ostensibly liberal guy, and what happened to him should send a shiver down the leg of anyone who is remotely interested in a free exchange of ideas.
Your line of reasoning is the perfect example of this: https://en.wikipedia.org/wiki/Paradox_of_tolerance
"Why are you tolerant people so intolerant of my desire for a world without all this tolerance? I thought you hypocrites were tolerant!!"
