You're right, feelings do matter, and this post did not dispute that. It's just that safety matters more.
It saddens me that the default interpretation of this is accusatory and requiring of defense. Not to personally blame you, this is very common and clearly a systemic reaction, but I don't know enough psychology/politics/sociology to understand why, just enough to know it's bad.
You have a completely different perspective than I. Yes, the Democratic party is being an ass to voters; yes, I hate them for what they're (not) doing; but I can slightly affect the odds to be slightly better for Palestine, so I will.
You can send a message that you're not a pawn, but they don't care, or at least in 4 years it won't matter anymore. If you want the best for Palestine, analyze your options for what's best, of which giving up and stepping back is not a very good one.
I'm not shaming you for not wanting to vote for him, I don't want to either, I'm trying to convince people that voting for him is in Palestine's best interest (better than Trump winning).
Oh that's definitely his fault, but you are presented 2 bad options and have chosen the worst one out of principle.
Please be practical. I want the best for Palestine, and unfortunately the best US presidential candidate for them with a chance of winning is Biden. "best" meaning least worst...
Send a message all you'd like, but I'd rather minimize the inevitable damage than say "told you so" while standing and watching everything burn.
Also worth noting, this is not mutually exclusive with other efforts! Keep pressuring the Democratic party, keep protesting, keep boycotting Israel-invested companies!
Pick something and change it when inspiration strikes. Sometimes you need a big picture view of something to get the right abstractions or even just name things.
Indentation implies there's some control structure causing it. Too many control structures nested gets hard to mentally keep track of. 3 is arbitrary, but in general more indentation => harder to understand, which is bad.
