I work at a major university, generally pretty left though, I have seen nothing but pro-Palestinian posters and slogans all over. In my town someone has put flyers around with the number of dead in Palestine since October 7th, no one touches them, but people have torn down pro-Isreali posters. Young people not connected to any political movement seem to be serious about this, I've never seen this amount of 'political' activity since living here. As long as I've known about the conflict in Palestine I've seen the majority of leftists be on the right side of the conflict, but I've never seen this amount of support or recognition from 'normies' if you will.
Since the attack on Oct 7th, people who may have heard of the issue but didn't have much concern are actually looking into the situation and realizing how horrific it is, and how guilty Isreal and it's supporters are.
