I don't think the person you're replying to is defending Biden. It isn't a defense of Biden's failure to act to say that Trump is, quite obviously, worse in every aspect. It is insane to think otherwise because the genocide got WORSE under Trump.
The point is that dipshits/losers/morons/accelerationists sit here and say both sides are bad, when one side is actively worse and they do not care that the one obviously worse side is killing multiple-folds more people while they pretend to smugly assert how good it must be to choose no evil while everyone else struggles to work with the hand they've been forcibly dealt.
You let me know when you step up and assassinate a billionaire, alright, bud? I'll respect your stance then.
