I don't know, I think you're being way too dismissive about many people's intentions.

I've had plenty of arguments here on HN about Israel, and it doesn't seem like most people are just antisemites. Many people have concrete, legitimate criticisms of Israel (and frankly, there's plenty to criticize.)

Sure, some could be motivated by antisemitism, but 99% of people? That doesn't seem right to me. At all.

(E.g. in most arguments, anyone even a little knowledgeable will argue specifically against settlements or against certain actions of the IDF, not just blanket "against Israel existing.")

While you may(or not) be right about rise in antisemitism, there also seems to be a lot more videos surfacing of stuff that doesn't reflect well on Israel. I consider myself pretty unbiased in this, I have absolutely no opinions about ethnicity etc and have often come to defense of Israel in some discussions but I can honestly say that my own view has soured a little bit. The killing(and denial) of that journalist, and that video of a funeral procession spring to mind. Starting to remind me of Northern Irish loyalists(who happen to revere Israel), which imo is a pretty ugly movement. Nothing about this is inherent to the people or country but (I think) like loyalism, comes from a degree of insecurity that can manifest as truculence
