I don't agree with other subreddits automatically banning people based on post history, but I can see why the subreddit was banned, along with the left leaning subreddit chapotraphouse which engaged in similar behaviour.
Even disregarding any content that may or may not have been on the subreddit, the ban happened (four?) months after the subreddit's mods had already locked it down and everyone had migrated to thedonald.win. The ban didn't actually have a purpose by the time they did it, so that reason was just an excuse to get rid of content they didn't like.
You say "issuing death threats" like it was mandated by the mods. As far as I could tell, the mods were doing what they could to keep everybody contained within their zone. And the premise of Reddit is that anybody can create their zone; if you don't like it, you don't have to view it.
My point is, the counterargument that they were banned due to bad behavior seems to be slightly misleading. Every sub has bad behavior, and I know for a fact (because I saw it!) that the mods were clamping down hard on anything remotely like what you mention. The community was downvoting such comments too.

Can you be more specific? /r/LateStageCapitalism is still up, and they seem to "issue death threats" just as frequently. For example, they frequently reference guillotines while gesturing towards the rich.
Also, there will be no unity. Everyone on the right-wing is doubling-down to oppose anything Biden plans on doing.
This Jan 6th march was actually planned weeks prior and many people were calling "for every able bodied man" to go to DC for the march.
Many more are planned.
