Criticism of Israel isn't inherently anti-semitic, but a lot of the criticism is anti semitic nonetheless.
I think we may criticise. But if that criticism holds Israelis to different standards that others, or is more critical of Israel than it is of other states commiting the same or worse crimes, then that post can be accused of anti semitism.
The amount of posts denying anti semitism while employing anti semetic tropes to attempt to make their point is frequently shocking to me.
If a Jewish person says that they feel your comment is anti sematic, I think we'd be better to interrogate ourselves as to why that would be. If a black person accused you of racism would you not honestly try to understand why they felt it was racist rather than immediately writing off their experience of what you said?
Ultimately, no one here can see into another's heart to see if they really hate Jews. But a lot of what is said certainly sounds anti semitic.
I think a lot of it is ignorance rather than hate, but the near constant shouting down of cries of anti semitism shows a lack of willingness to learn and listen.
