This should be self explanatory. Jewish spaces are Jewish spaces. If you are NOT Jewish (and yeah, I'm including you, Messianics), it is not your space. Gentiles, no matter how much you love our religion or culture or whatever, even if you've decided to live by the Noachide laws, this is NOT your space and you are not to enter it unless invited by Jews. Even then, recognize your position. You do not have the right to talk over us. You do not have the right to make halachic proclamations. You do not have the right to decide who we include in our spaces. And don't you dare try to lecture us on halachic law. Even within Orthodox Judaism alone you will find millions of different interpretations. Add to that regional minhag, regional differences, interpretations of observance, whether 'barrier mitzvot' are or are not full commandments, and there are a lot of right answers to a single question. And even among the most orthodox of orthodox, they will admit that they aren't sure and are just trying their best. So don't you Goyim, and I am talking extra loudly to the Messianics and Noachides in the crowd, DARE to try and police our Judaism and our Jewish spaces.
