a) It really makes me question this whole "holocaust" thing, and b) it really looks to me like racism and antisemitism are false charges created to stifle dissent against the state!

Not on you, but unfortunately, it probably works on enough people, or they'd stop doing it.

Now compare that to someone calling another person a heretic. That will only make the guy saying it look bad. Things need to change so that calling someone a racist etc. is the same as calling someone a witch or a heretic.
