Well, the "worst" side has currently returned to power, the other hasn't. There's no reason to belive that the other side wouldn't become worse in its own way to further solidify its power. Before you talk about priors, remember that Trump's 1st turn also wasn't as unhinged as this. While it is okay, perhaps advisable, to temporarily support the current less worse side, try to not build house for people that would gladly step on you once your usefulness runs out. As OP said: it's a small club, and you ain't in it.

>I don't think "both sides" works very well when one side has been supporting the murder of citizens for exercising their free speech

Obama was murdering US citizens for exercising their free speech, and their children, more than a decade ago.

>But of the options currently available, one is much less bad than the other.

If one person says they are going to stab 99 people and the other person says they are going to stab 100 people, you could argue that the guy who stabs 99 people isn't as bad, but I won't ever support either one of them or consider them worthwhile no matter how many others do.
