I bet you’ve been keeping that dunk in your pocket for a while and you were so excited to use it, but I don’t think you understood the comment you were replying to.

That dunk is for when someone replaces one word with another to make it seem bad. The comment you replied to was pointing out that you had simply replaced the standard Western TM anticommunism with a more refined anticommunism, which you express as “anti-tankies”

you get that "tankie" and "communist" as a pejorative are functionally identical, right? Coincidentally, they're also basically the same as "woke" as far as pejoratives go.
