my family isnt zionist so i havent really had to argue with them about palestine and so idk if i can give you perfect advice on how to talk to someone whos close to you about this, maybe some of my followers can add stuff
but still ill say this, (if theyre jewish) a big part of it is the emotional connection people have in light of the history of the holocaust, and like a visceral feeling of fear, which is purposefully imprinted onto peoples communities. so i think dismantling all the myths that israel has specifically about the holocaust and jewish safety might make them question this? its unfortunate but i think a lot of zionists wont react well if you talk about the amount of violence and dispossession palestinians face just because theyve already been dehumanized in their mind, and they genuinely feel that these people want to kill them for being jewish, and israel is the only way to ensure jewish safety, so you have to get past that first. im not sure what their perspective is on israel and why theyre a zionist, so idk. but showing people that israel is not actually protecting jews, its protecting european and american interests in the region and was supported by europeans literally as a solution to their "jewish question", especially with the vast amounts of jewish holocaust survivors in refugee camps in europe for years after the war. like ask the question why do all these european governments put tons of financial and military aid to israel instead of helping their jewish diaspora communities thrive and attract people to them? why do they actually make things harder for jews and have shitty convoluted policies for european jews who were expelled to return, but also support israel? is this something thats really good for us? also learning about how apathetic and even pro nazi america was during ww2, and how much holocaust revisionism they engage in to make themselves look historically better and twist their reasons for supporting israel, really made me feel like the us government line on israel is just ridiculous hypocrisy. ive made some posts about this which ill try to find
