two things can both be unacceptably bad, without being equally bad. The problem with "lesser evilism" as a political philosophy is the existence of a "worse thing" is used to justify an unacceptably bad thing.
You don't need to find a "balance" here - you can just say "the way recent Democratic administrations have aided and empowered slow genocide against Palestinians by Israel is unacceptable and barbaric; also, Republicans have been notably worse too."
That's just being honest.
It's okay to look at the historical record and say "holy shit, all of this is bad, and look at how much shittier it got when Reagan, Bush and Trump were in charge"
And imho, if you look at that historical record of US govt aiding Israeli genocide, that's what you'll see.
The key thing is to understand framing, context and depth - the media doesn't "lie" in a traditional sense as often as most people think they do - there's a practiced technique involved here that goes beyond mere "lying" - which isn't to say they won't just outright lie sometimes
Framing is about presenting the story in a way that read straight without nuance, is technically true but often false in any real practical sense. And these guys are fucking pros man, they can put clusters of ideas in your head with a mere word, altering the order of presentation
I can take someone's words, or response to a crisis, and depending on how I frame the "reporting" of those words, I can make you want to believe it, or make you want to disbelieve it, so easily - just by changing a few small words, breaking out a thesaurus.
