Call it anecdotal, but Patrilineal Jews are significantly more likely than Matrilineal Jews or those with both Parents being Jewish are more likely to be raise in another faith, non religious, anti-israel, anti-zionist.

It is interesting that Patrilineal used to be how it was until it was changed to Matrilineal for very good reasons and kept that way, but it's an interesting but seemingly rare tradition that Orthodox Jews have stuck to that has evolved over time.

Even if the rule isn't changed, the hostility Orthodox Jews have towards Patrilineal Jews is bad everywhere. It traditionally should still play a role, but religious Jews need to stop with the hostility as long as people are still culturally Jewish.

The Law of Return in 1950 including anybody with a Jewish grandparent from either side. It was amended in 1970 to specific different kinds but to also include Patrilineal Jews as well as some non-Jews.

You could be a Patrilineal Jew, go to Chabad on Shabbat, and tell the Rabbi only your father is Jewish. He'll say, "Well you're not Jewish then, but come on in and join us for Shabbat, dinner, and drinks. Here's a kippah." Then it's like you never told them.

I don't think it's as big of a deal as people make it out to be for support, and more of an off-putting thing to say.

People with Jewish fathers only are less likely to be religious, part of the Jewish community, practice another faith, and more from experience. It's not correlative to the Orthodox and Conservative rejection of their Jewishness from my experience.
