This is an interesting point. Its well known Judaism in not an ethnic class, but a religion. Its also well known that religion is a set of beliefs, and to speak out against that religion (be it insulting it, or argueing against it), is our right, as we are all as Humans entitled to freedom of speech, to speak out against beliefs.
On the contrary, insulting Judaism is "Anti-Semetic", apparently a "crime against humanity" as once said by various statesmen notably Erdogan. Do you believe Judaism should be protected by such special laws? Is all this actually infringing on ones freedom of speech? What do you think?
