I actually was trying to figure out how Lemmy works, so I had a lemmygrad account, and a lemmy.ml account. I believe I posted the original using my lemmy.ml account and then when I was logged in to my lemmygrad account I posted the comment you screenshotted there.
That comment was in reply to them thinking I was someone else that must have been a problem in the past. And it's also me venting a bit about how tankies typically don't want to discuss anything, they just want to call you names and boot you. I realized after the first few walls of text came in that there was not going to be any discussion to be had in that thread.
Anyway, I'm so frustrated by the lack of sense of humor that tankies have. As a "lib" it's funny to me that they won't just own the "tankie" epithet and embrace it. The denial and defensiveness is what's frustrating and hilarious to me.
I'm not "taking potshots" at tankies. Tankies know where they stand with me. They just don't seem to have any sense of humor about anything other than "dunking on libs".
