None of them are parody. Some of them feel like parody, but the poster is dead serious.

If these were supposed to be parody, we’d see a few that weren’t subtle. If they were just riffing, some would be so hyperbolic that there would be no doubt that the poster wasn’t being serious.

Instead we have a mix of memes that either kinda feel like a joke, or come across as completely serious. We can assume that whoever uploaded these earnestly identifies with each of these.

That person is extremely stupid. Dangerously stupid, even.
