The law you're quoting, HB 741, commands the Florida public education system to treat anti-semitism the same way it treats racial discrimination, and it adds religion to the list of characteristics public schools (and private schools that receive government funds) can't discriminate against -- a list that already included race. So in what way is DeSantis treating the black plight as different from the Jewish one? It seems like he was going to some effort to treat those plights the same.
Your reply seems to be missing the part where CS/CS/HB 741 protects Jews from discrimination (which is awesome) while SB-148 protects white people from their own feelings.
As far as I can tell SB 148 protects people of all races and religions from discrimination. Do you see anything in lines 44-78 -- the list of actions it defines as legally discriminatory -- that you think are not in fact discriminatory? Conversely, as far as I can tell it doesn't protect anyone from their own feelings. The rest of the bill contains among other things an expression of the legislature's disapproval of hurting people's feelings, but I don't see where it does anything substantive about it. And as I think you noted upthread, some of that stuff they said they disapproved of would make you feel bad too. So if the schools do take that part to heart and refrain from teaching in a way the legislators disapprove of, that would protect you from your feelings too, not just white people from theirs (if we pretend for the sake of discussion that you're still in school.)
It also doesn't help that there is ABSOLUTELY NO PROOF that CRT (whatever that means to some white people) is/was being taught in Florida Schools or being utilized by private corporations.
What's that got to do with the price of tea in China? The bill doesn't mention CRT. The specific kinds of teaching the bill makes actionable are spelled out; the CRT fans will vociferously deny that CRT promotes those kinds of teaching; and whether it does or not has no bearing on whether a teacher should teach those ways. A teacher who teaches in those ways might have been inspired to by CRT or by something else, and the source doesn't matter.
With that said, has DeSantis signed any bills that can be remotely construed to be providing protection for antisemites against feeling discomfort, guilt & anguish about Jewish history?
Almost certainly -- any bill can be remotely construed any way the remote construer pleases. This thread provides numerous examples.
Be that as it may, you appear to be making an analogy between white people and antisemites. That seems like a flawed analogy to me, since being white doesn't make one anti- anything. As far as I know, De Santis hasn't signed any bills to protect antisemites from anti-antisemite teaching, while he has signed a bill to protect white people from anti-white-people teaching*. But if one were to separate out the white people who are antiblack and analogize antisemites to only that subset of white people, then DeSantis' treatment looks even-handed. As far as I know he has not signed any bill to protect antiblacks from anti-antiblack teaching. For example, if a Florida teacher teaches that non-antiblack people are morally superior to antiblack people, and that an antiblack person by virtue of his antiblackness is inherently racist and oppressive, and that an individual should feel discomfort, guilt, anguish and psychological distress over his antiblackness, SB 148 does not define that teaching as discriminatory.
