I think most of it is just confusion inherent in the term "antisemitism", which TBH is a bad term because it singles out a single Semitic people among many as the oppressed ones. That false focus then in turn causes a knee-jerk pendulum swing towards another extreme.
And who's to blame? Again, Germans: The term was introduced to replace "Judenhass" (jew hatred) with something "more scientific sounding", as recently as 1879. Damn that's a lot of citations there. Maybe we should switch to "Jewphobia" or something.
Ha! If only. They at most had WAP browsers and noone was using them because you paid like five bucks per transferred byte.
