There are people saying that someone with a jewish father may not be Jewish. WHAT?
You lost a lot of credibility with that statement. Being Jewish is not a “feel-good” thing. A person from a Jewish father and a non-Jewish mother is not Jewish, no matter how (s)he may feel about it. Such a person, who cares about following the Mitzvos and would like to convert, would be welcomed with open arms. But Halacha is non-negotiable, no matter how politically incorrect it may be.
