You're right. I miswrote. I will concede that leftwingers never insist on no intergroup differences. What actually happens is that the moment you even bring up the question, they go into "label and destroy" mode. Which means they call you names and focus on harming and silencing you. They never engage with the content of the discussion, unless you're good friends talking in private, so there's no need for them to insist on anything.

Please dont' try to deny the consequences at play here.

We live in an extremely heavily-policed overton window on these issues and there are serious consequences in play.

If you go and start asking, talking, and posting about e.g. IQ differences between races, it will seriously impact any career in tech, media, academia, law, education, and basically any other high-status field. It'll also seriously impact your social life in any city in America.

If you matter at all you'll also attract a cloud of motivated online harassers who will contact your employer, friends, spouse all trying to damage you as much as possible.

This is true even if you never make "unsupported claims that particular outcome differences are due to such differences". It's very easy to support such claims, since there's extremely strong evidence of a causal link from IQ to outcome differences, and there is similarly strong evidence that IQ is linked to group genetics.

And it's impossible to talk about IQ of population groups without people assuming you're making such claims about outcome differences, or putting those words in your mouth so they can come after you.
