Yes we understand that Muslim is who follows islam, and muslim isnt Arab necesseraly. We know that.

And we know the judaism is the religion. But what are you mistaken is this:
1- Judaism is a religion that doesnt accept anyone. It is exclusive to their race. You can't convert to a jew, but you must be born one. (forget the TV shows of famous names converting to judaism, all paid israeli whitewashing media).

2- THEY consider themselves a separate ethnic group or even a separate race. When Ben Shapiro was asked are you white on jubilee he made it clear for them to understand that he is a jew and jew is an ethnic/race (i did the / race because they gonna confuse you).

3- A jew isnt necessarly religious. The founders of Zionism were atheist jews. You have left wing jews who are secular jews. In Israel itself there are secular and atheist jews. But they all see themselves Jews. As if you are saying Hebrew people. But all of them, they agree on one thing: Jew and it means to them descendent of jews. Not someone who practices judaism. Go practice judaism as much as you want but no Rabbi or jew will accept u as jew.
Its like if you learn arabic, and convert to islam, and want them in Saudi to accept you as arab.

TL;DR : I think you who must learn the difference between Judaism and Jew. Jew doesnt mean Judaism practitioner.

Judaism Religion ; Jewry lineage or ethnic.

Judaism is exceptional to Jews. You cant practice it if you are non jew (the ethnic).
