Boiling down to fundamentals I've encountered two types of arguments in the past few weeks:
Hamas is beheading babies, so retaliation makes sense, Israel has a right to defend itself, Jewish people are entitled to their homeland
deranged, out of touch with reality, historically ignorant
Well Hamas is a conservative islamic organization led by dudes living in Qatar, so they would just create their own apartheid ethnostate lead by rich palestinians
this is just bizarre radlib bothsidesing using a hypothetical outcome to Hamas winning and them not being perfect secular social democrats
And this made me realize that the biggest propaganda achievement by Israel and the US has been convincing people that this is between Israel and Hamas, and not an anti-apartheid insurrection that happens to be led by Hamas among others.
"Anyway, the only thing we can do when we see an apartheid state is to wait until the oppressed people have the perfect grassroots leftist movement not contaminated by either rich people or conservatives, a movement that isn't targeted for assassinations by the CIA and MOSSAD; and then when they rise, we should cheer for them from the sidelines as they try to seize power from a nuclear-powered, genocidal apartheid state supported by some of the richest countries in the world. This represents the principled leftist position."
