~70% of communication is nonverbal. Body language and tone of voice convey that you intend something opposite of the literal words you're using. When you throw the nonverbal aspect out the window for an entirely verbal exchange, especially online where everybody is a stranger and potentially something akin to but not necessarily a Nazi, it's pretty difficult to ascertain whether you're dealing with somebody who is broadcasting silly thoughts to satirically display the stupidity and absurdity of supporting fascism or an actual supporter of fascism who is actually stupid and absurd. Without using italics or "/s" we can't know for sure because there are almost certainly some dipshits who believe whatever you say sarcastically without a shred of self awareness.

But yeah, I think the comment you're talking about was pretty obviously meant to be sarcasm. It could only be misunderstood by people who don't know what those words mean lol.

At first I thought lemmygrad was a satirical instance making fun of communist talking points by exaggerating them...

So yeah, sometimes it's hard to distinguish.
