That is indeed quite a weird restriction. Sure that law was made by Jews? I think many would oppose such a move. On the other hand some feel compelled to enact such laws because there are groups tell funny stories about Jews or Israel. Any more examples?
Help for hurricane relief, as weird as it may be, doesn't indicate political influence, although many states have special protections for minorities of all kind.
This one favors them but is not targeted to American Jews rather Israelis.
Boycotting Israel is not about telling funny stories about Jews. I suggest you read a little about why the boycott exists in the first place if you truly want to know.
I had no idea Israelis thousands of miles away are considered minorities in states like Texas and Georgia and many others.
There is also a restriction on working for the state that you must not boycott Israel.
This is as clear as day that its a violation of free speech by gov actors.
I think BDS is not a feasible strategy but I am firmly against silencing them in any way.
That said, ask some Jews what they think about such policies. Again, this isn't indicative of anything aside from maybe a misaligned strategy to shield minorities.

There are countless many examples like this.
