And what Hamas is trying to accomplish is also genocide - but this is all besides the point. The larger question is this: what would it take for you to believe even a fraction of what the Israeli military claims?
Can it be true that the IDF is indiscriminately killing Palestinian civilians as well as telling the truth?
Would you claim that Hamas is justified in their killing of civilians if the Israeli military also kills civilians?
Even further: what happens if all foreign governments stop sending aid to Israel and Lebanon/Hamas/etc. attack Israeli citizens with the intent of purging them? Would you suddenly support the IDF in it’s struggle to protect Israeli citizens from these groups who have already made it clear that their primary purpose is the genocide of the Jews in the Levant?
Regardless of anyone’s feelings on the IDF, it is incumbent on all of us to take the claims of Hamas and Israel with a massive grain of salt - you may not believe in the credibility of the IDF but you certainly cannot dismiss the engrained antisemitism of Hamas and others in the region and believe them at face value.
But you are making a choice: you’re choosing to only let observable facts influence your beliefs. Everyone is an atheist by default, and most of them are then told to believe what they’re told from birth, but at some point people make a conscious choice on how information is prioritized. Humans aren’t read-only and I would say it’s a safe bet that most people have the opportunity to influence their own beliefs and act accordingly. Obviously if someone is abused and doesn’t develop mentally, then yeah, don’t hate the person but don’t necessarily give up on helping that person develop, either
