Personally, I don’t think the commenter was wrong to point it out. This isn’t an even conflict and Israel is not only attacking Hamas. “Pro-Palestine” implies you’re choosing a side in this conflict and allows people to form a bias. Anti-genocide showcases exactly why the majority of people are against the war.
I see where you’re coming from but at the end of the day “Pro-Palestine” implies that these people are only protesting it for Palestine, and not the genocide. If the situation were reversed where Palestine was committing a genocide against the Israeli people then these people would not be “Pro-Palestine”. Remember, a lot of people around the world think that Palestinians want to ethnically cleanse the Jews (which is 100% not true). They use this as an excuse to justify what Israel is currently doing. This is what I meant by saying it has an implicit bias. It’s a very polarizing situation and the media is making it worse by labelling everyone either Pro-Israel or Pro-Palestine. We’re meant to believe that by picking a side you forsake the other. Which is not the case for a lot of people.
