Laws that protect one group of people or otherwise infringe on free speech in any fashion are unconstitutional to begin with, so agreed.

As for "anti-semitism", that -- like racist, sexist, X-phobic/Y-phobic, etc. -- is just used to try and bully people into submission, because it works...or worked.

Everything defending those laws are just criminals in a special seat, and I really don't care who it is that would push a blatantly unconstitutional law, such as the suppression of free speech that's "mean", they are an enemy of the Constitution period.
