Totally fair. As a student of ancient languages, I primarily think of it in terms of language development and archeology, so I can certainly see why its modern connotation would be spurned. I think that, since the term's misuse came out of the bullshit archeology of Nazi Germany, it's better to air it out for the bullshit it is.

Consider also that "Semitic" is a philological term for the languages of the varied peoples of the Arabian peninsula and the Levant, so for an Israeli politician to claim that Palestinians are "antisemitic" is hilariously stupid. There are a lot of uses of these old archeological terms and symbols that got corrupted when the Nazis first did their Nazi thing, and my hope is to disempower their rhetoric by contributing to the disempowerment of the bullshit they spawned.

I personally think it's just hilarious that the term for "white, blonde, and blue-eyed" among racial purists literally refers to a heritage that virtually cannot be further from their supposed "ideal". It is for this reason that I correct people, because it is just another case of Nazis and White Supremacists showing that not only do they know nothing, they actively look less intelligent with every word they spew. The more people who realize that the Nazis are wrong, the better. In the case of the thread OP to whom I replied, it seemed like an opportunity to pass on this tidbit, because their stance makes me think that they and I are like-minded in our opinion of Nazi idiocy.
