Waton was an ardent defender of Jews and Judaism against Hitler and anti-semites.
And Hitler was an ardent "defender" of Aryans and gentiles against Jews and Judaism.
The problem, in both cases, being that ardent defence against a people who pose an
imaginary or
non-existent threat is disastrously morally wrong, just as ardent defence against a people who pose a real threat is a moral imperative.
Hitler was obviously a threat to Jews, but is now dead. Anti-semites are a threat to Jews by definition; But that makes a false accusation of anti-semitism into a weapon or threat that anyone with a zionist agenda can wield, invoking the ghost of Hitler. This weapon is all the more powerful, because anti-semitic threats against Jews are a real thing that is currently out there; But with great power comes great responsibility.
To call someone out as anti-semitic, without hard evidence that they actually dislike Jews - not any individual Jew, but Jews
as a class - is simply a variation on the theme of "Everyone I don't agree with is Hitler".
And ardent defence against non-threats, or even against trivial threats, is a significant threat in its own right.
The defining factor that makes Hitler an immoral and evil person is his ardent defence against a threat that never existed. To avoid becoming like Hitler, it matters not one whit whether our side, team, or tribe includes Jews; What matters is that our side, team, or tribe needs to include people who are being attacked
without just cause. Only then is it morally acceptable to use violence, or calls to violence, in their defence.
And only then is it correct to assert our moral superiority over their assailant(s).
Moral superiority derives from being less inclined to call for (or actually employ) violence, or simply being less inclined to denigrate or belittle, than others.
Anyone can invent (or massively exaggerate) a threat, call for violent resistance against it, and claim a spurious moral justification for their fear and hatred.
Escalation is immoral; De-escalation is virtuous. Tribalism is therefore immoral; As is any effort to give significance or importance to the trivial markers of tribal loyalty that we call "religion" and "race".
No religion nor race lacks the ability to be racially or religiously intolerant, and it is the intolerance that is the problem, never the identity of the intolerant group, nor that of their scapegoats.
