This is not why Judaism is hesitant towards converts
Its because of how they conceptualize themselves.
Rea meaning neighbor or fellow citizen, etc. basically, your people, is made up of other Jews who are you literally related to
And the opposite of the Rea are the Zara the foreign, the non-Jew
Historically the zara are the Greeks and Christians but not the Muslims for some reason
To them being a Jew is being a part of that community and not participating in what is zara
The Jews almost ceased to exist after the rise of Christianity and really only survived because of the Mishnah and later the Masoretes writing down their religious traditions, but there was a period late antiquity where their traditions existed precariously through a relatively small community of oral tradition.
So make no mistake you are not really wanted as a Jew among the Jews because you are not a Jew.
its a game of nations to them, its blood not faith or works
And I would argue that sure you could try to be like Jewish as a religious practicioner but in reality it makes more sense if someone is like an important part of a community of Jews, but somehow is not a Jew, and maybe marries someone who is a Jew, but every nation ever had exceptions. Maybe Druze or nonreligious Arabs in israel find themselves in this situation. Otherwise its kinda weird to convert to judaism.
And honestly the real reason they don't really want converts is because you aren't a Jew tbh
My first wife was an Ashkenazi Jew, and there was ZERO pressure for me to convert. Everyone always treated my sons very well and I imagine that was because of halakha stating that they were Jews, but there was almost a respect I got as a gentile for not being a poseur and converting.
I was raised Roman Catholic like a good little American Irish boy, and the two things that I got a lot of love in that community for were standing up for my kids and other Jewish family members when they were being fucked with, and for never putting on a façade and acting like I wanted to become an oven dodger.
I can understand if you took a 23andMe or an ancestry test and your shit came back like 90% ethnic Jew, but converting for the goof is just weird.
They probably dug me so much because I fucked the Tay-Sachs right out of her bloodline lol. And I mean make no mistake, I still felt like an outsider looking in, but they never treated my son's like that and they also never made me feel not welcome or not loved. It was just kind of unspoken that I wasn't one of them, so I don't think abandoning my own beliefs for some phony conversion would have helped that at all.
Reason: Also, don't let that green redditor fool you, Jews are NOT accepting of faygelehs.
