I think they're asserting that the more considered comments (unlike their screeching contentless insults) aren't 'real Anarchists' and don't usually post in those subreddits.

Which is pretty rich considering that they'e made maybe a dozen posts across Reddit total in a year until this little crusade and most of them are also screeching, insulting meme posts.

They're also constructing a narrative that they're being brigaded by an army of tankies on a post with maybe three other commentators total, who are basically asking why they're being weird.

Honestly, that person desperately needs to get offline and find a way to help themselves.
