Unless I'm very much mistaken neither *genuine* Christians nor *genuine* Jews accept the validity of "gay pride".
Ben Shapiro makes that same point. As he says — a lot of Jews are not Jews. He means that many people with an ethnic Jewish heritage don’t care about Judaism at all and may in fact be hostile to religion and/or Israel. But they identify as Jews.
It’s somewhat complicated, in that our religion does, indeed have tribal elements to it.
I didn’t really intellectually understand this until I participated in the conversion of a young man whose father was Jewish at a Chabad in college. Part of being Jewish is joining the “Jewish people”.
So there can be Jewish people who are apostates, like most Reform and social Jews.
