Really seems like the left built their entire narrative on the "replacement theory" thing, under the idea that when people start talking about it they could simply go "oh noes you're not allowed to talk about this it's dangerous!".

Like a hyperaggressive motte-and-bailey thing, rather than just defending you proactively attack and eliminate talk of describing literally what you're doing.

I would mention again that the shooters reddit account included stuff like "I hate white people" and comments that bipoc are superior to white people, along with covid "how can you kill grandma" type hysteria. He's like the quintessential "I support the (latest thing)" poster.
