There’s questioning the credibility of whether people are outright lying (which people “reporting” on Gaza do all the time) and there’s simply pointing out that even if you believe stories at face value, the conclusions do not make sense.
A doctor in a hospital who sees a gunshot victim brought in cannot possibly look at the wound and somehow know, from a physical examination of the injury, who shot the person and under what circumstances. Taking the testimony of the “Gaza doctors” at its word, that is what they claim to be doing, and it’s absurd.
Not everyone who is willing to believe the constant stream of implausible nonsense from Gaza is an anti-Semite. There are lots of reasons people choose to be gullible. I think people who, simultaneously, advocate believing everything Hamas and the “Gaza doctors” say no matter how unfounded or inherently ridiculous, and argue that it’s good for Arab Muslims in Amsterdam to roam the streets in a Jew Hunt, probably are racists against Jews in most cases.
A good test for whether people are “Anti-Zionist Not Anti-Semitic Just Doing Legitimate Criticism Of Israeli Policy I Swear!!!” is whether they do, in fact, limit their criticism to Israeli policies, as opposed to rejecting wholesale the notion that Jews on the Asian landmass have any right to self-defense at all, or justifying a Jew Hunt that looks for anyone wearing a black hat in Amsterdam or Antwerp to beat.
I definitely think that if the sort of attitude displayed towards Jewish civilians in Europe (aka the “the people who eagerly weaponize their own victimhood”) by MrDibble was directed at any other group, there would be no debate whatsoever about whether it constituted racism.
