Yeah, you can twist the last 2 into a political position. But given the context, they seem to me to be appeals to violence.
I mean look at just a few tweets down on the same pro gun user:

How is this not inciting violence? What else could "seizing the means of production" possibly mean in a tweet that literally shows off his/her set of assault weapons?
Or literally talking about killing pigs?

I absolutely don't disagree that there are racial problems that we need to solve, or that the police need reforming. All I'm saying is that by not acknowledging that maybe this needs dealing with too, we are still going to have backlash by the other side.
The second two are pro gun ownership - which would be perceived as appeals to violence in most of the world, but in the US is a perfectly common political position.
So this fails to support your false equivalence re: Parler and Twitter.
There's actually plenty of extremist hate filled bile on twitter, but these are terrible examples. Search "#killallmen" for some readily accessible examples.
Still, kind of absurd to suggest it represents the mainstay of content on the platform.
