All depends on who’s saying it, since you get an idea of intent:

Leftist: Funny, cuz you know they’re not being completely srs

Shitlib: Unfunny, cuz you know they’re saying “tankie” (And believe all it implies) without a hint of irony

Also it looks like that user is literally the only one who makes posts in that anti-“tankie” comm, which is funny. It’s basically just a personal rage comm
