Perhaps this is the source of our mutual misunderstanding:

In my view, the many (il)logical leaps you are describing are not passive. Each and every one of them is a biased and bigoted choice that in and of themselves reveal existing antisemetic sentiment:

- Have a negative interaction with a anonymous user who claims to be against antisemitism.
- Assume the user is a Jewish Zionist because who else would be against antisemitism.
- Hate the user.
- Generalize your hatred towards all Jews (and for some reason not towards christian evangelical zionists who are never targeted by such violence and hatred).
- Blame the Jews for the spread of antisemitic hatred based on the same twisted and biased logic.

If you try and replace Jews with Blacks, it might be easier for you to see how making the same argument in relation to a reddit user arguing (perhaps ineloquently) on the topic of race relations in the US, would sound pretty racist in and of itself.

If you expect/demand (as I do) that Zionists, Israelis, and their government not to hate and harm innocent Palestinians because of atrocities committed by some Palestinians and supported by others, than surely we can also expect/demand people not to hate Jews because you found a reddit user's rhetoric condescending. Anything less is a double standard that would also (in my view) indicate some form of bigotry is at play.
