This argument then is going absolutely nowhere. I suggest you just stop posting replies to him if you assume he's lying to you about everything. I'll just note this response by him:

"Responsible for perpetuating a political philosophy that’s influenced a generation of smug know-nothing neoliberal trash that’s done nothing but continue the US down a trajectory of stagnation and will help usher in a century of humiliation and genocide."

A MAGA would not say this.

I'm really not interested in going down the rabbit-hole here on this with this user - but I have no reason to believe they're lying. I suspect I could probably look into this users posting history and confirm consistency here, but speaking generally - opposition to democrats/centrists/liberals (insert any other terms you like) also comes from the some of the left. Hell, if you're on Lemmy you must be well aware of this given some of its more controversial instances are full of them.

You might consider them useful idiots, or you might not. But they are genuine. But the broader point is that there's not much point going at it with a user who you think is just lying to you.

I was just pointing out how ridiculous your tact is. Oh I don’t like this person, better call them MAGA! Anyone can do that. What was it you said about a duck? Think that could apply here too.
