The people accusing the OP of antisemitism before the thread got rewritten and also, the people accusing back the original accusator.
The exact names are not worth hunting down, it appears to be some overreaction caused by tunnel vision with no malice intended from any side. The important thing to note is that both one should not jump to conclusions based on a short bad behavior, and that just because you are hurt, it does not give you the right to go after innocent people.
I don't believe anybody accused the OP of antisemitism. What I see is, "It raises an antisemitism caution flag whether the speaker intended to or not." That's manifestly not an accusation. Do you see something different?
But either way, one should not go around accusing people at random.
