in reply to geneva_convenience • • •I dont know the song but picking a side in that matter seems to come with bad consequences. This has been like that for decades already.
Both sides handle things wrong but since oct 7 i kind of understand israel. Flotilla activists et. al completely forget that and that hamas was iran financed which literally swore to make jews extinct.

in reply to Waterpumpee • • •Hamas was also financed by Israel in order to sink the efforts of the PLO. The secular PLO looked like it might actually get some peaceful recognition of statehood and Israel knew a violent Islamist leadership would torpedo that. Israel has been fighting against Palestinian statehood, limiting movement of Palestinians, controlling resources, supporting "settler" bandits that colonize and kill Palestinians, etc.
Israel has been slowly taking over Palestinian land and killing their people for decades. The Palestinians can't vote in Israeli elections. Their statehood has been blocked by Israel so they have limited diplomatic solutions. What peaceful option do you propose they should have done?
The Oct 7 attacks killed about 1200 Israeli civilians and soldiers. In response, Israel has killed 1200 Hamas militants and 82,000 civilians, wounded a further 174,000, blocked humanitarian aid, leveled apartments, hospitals, schools, etc. Acting like both sides are bad when one is fighting for survival, and the other is committing a genocide is just arguing in support of genocide. If you're somehow still ignorant on this topic, I suggest you do some more digging into the history of Israel and Palestine. If you have learned about it and still support Israel then go fuck yourself.
