Also, the OP reads as a sarcastic joke by being an in the format of an over-the-top copypasta about anti-semitism.

I agree. This feels in poor taste.

"Oh, am I late to the antisemitism struggle session? Let's reframe it as a copypasta bit to prove my solidarity and elide any substantive discourse."

Especially when you're quoting Stalin, who's got a checkered history with antisemitism.
