To be absolutely clear to anyone who runs across this, this person has been banned from our instance, you don't need to report it again. The only reason this reply is still up, is for others to see all the ways in which this person is wrong and the whole they dug themselves when they did reply to someone and were rightfully reported and ejected from our instance.

Grievance studies (Critical race theory, queer theory, and other ideologies based in post modern belief systems), for instance, are eroding many useful and productive enlightenment ideas.

Have you studied any of these yourself? Or are you relying on characterizations of them you heard in media?

Color blindness is a legitimate way to reduce racism.

In theory, sure. But in practice it often gets used as a rug to sweep racism under.

Instead, leftists believe they should elevate group identity at all costs, thereby expanding and heightening racism.

Keep on mind this is a society where certain groups have been marginalized and terrorized for decades or even centuries. "Elevating" them is only a reaction to that long-entrenched bigotry. But (what's that quote?...) when you're accustomed to privilege, equality feels like oppression. Attempting to bring historically marginalized groups into equal footing with mainstream groups probably will look like they're being "elevated" to the people who enjoy the privilege of being accepted broadly by default.

Queer theory denies human physiology, elevating the idea that everything is socially constructed

You're already getting pushback on your other points, so I thought I would weigh in here. Biologically speaking, sex is multifaceted, variable, and somewhat malleable. Even anatomically or physiologically scientists say that gender and sex are not as simple or clean cut as you are making it out to be. Additionally, gender diverse people can be found across all cultures and throughout history - transgender people are not an invention of the post-modern era.

I don't think that acknowledging the reality that human experience is complex and multi-faceted is a left wing value. It is evident to anyone who honestly engages with scientific consensus and with the lived experiences of LGBTQ folks that those people exist. They're not going anywhere, and I don't think it's especially "left wing" to say we ought to make space for them in society to just live their lives as they are.

Colour blindness is not a way of combatting racism.

If you have a real world system, and you bias it heavily to be unequal, then you try and correct it by biasing it to be equal, the average output is still vastly unequal, and the absolute best case scenario you can hope for is that it will trend towards equality over time without ever reaching it.

There's a reason that people who actually study and think about the topic come out as antiracist and people who don't think it about it except when it inconveniences them just wish everyone would stop talking about it and we could pretend like it didn't exist.

Wow, what a shocking comment. Explains your original I suppose.

You can’t just lay judgement on something because you don’t like it. You need to actually understand it, hopefully your read the other responses you got with an open mind, lest ye drift deeper into bigotry via ignorance (chosen ignorance, at that)
