Honestly this is a big problem with being able to criticize Isreal in good faith - it’s all too easy to be taken as an antisemite.
Don’t get me wrong, I’m sure loads of antisemites are out there pretending to be concerned about Gaza while actually just using it as an excuse to hate jews - but the OP is describing very real issues - like the thing with Havard just last week where companies were rescinding job offers based on who supported Gaza and condemned Isreal
