Hasbara is so gross because it's just Zionists throwing walls of language at you to convince you you're not seeing what you're seeing.
You see raw video footage of the most horrifying thing imaginable in Gaza, and then you see them in the replies going "This is actually fine and normal because words words words words words words words."
You see a news report about Israel doing something astonishingly evil in Lebanon, and there they are underneath it going "There's actually a lot more to the story because words words words words words words words."
You see some far right Israeli minister spouting nakedly genocidal rhetoric, and they're swarming all over it saying "Well this isn't actually what it looks like because words words words words words words words."
You see every major human rights group on earth saying Israel is guilty of genocide and apartheid, and they're running around frantically telling you it's a giant conspiracy to frame Israel and the truth is that words words words words words words words.
You see more and more mainstream news institutions reporting on the mountains of evidence of widespread rape and torture in Israeli prisons, and they saturate the airwaves claiming it's an antisemitic blood libel because words words words words words words words.
The idea is to just pound your intellect with a firehose of verbiage until your inner sensemaker has been shredded and you're too confused to form a coherent picture of what's actually going on. It's a disgusting, abusive, and profoundly unethical thing to do to people.
But the good news is it's not working anymore. Language is immensely powerful, but its power has its limits. Israel's behavior has become so transparently unacceptable that no amount of word magic can manipulate people into seeing anything other than what's happening in front of their face.
