Baalie teshuvas years ago usually had a better chance of integrating within the frum community because the moral decay in the secular world wasn’t that bad, so there wasn’t so much suspicion regarding the BT’s.
Also most baalei teshuvas years ago (I’m not talking about Russian baalei teshuvas which is a seperate category) became frum because they were attracted to Yiddishkeit or simply attended a frum school.
Today there is this mass movement to freneticly grab any person who claims they are Jewish and influence them to become frum, in an effort to stem the imagined total dissapearance of frum Jewry.
Granted, in the secular world assimilation is tragic and of immense proportions. But the cutting off of a large percentage of Jews from klal Yisroel is not a new phenomenon. It happened quite a few times in history.
The frum community is b”H growing nicely.
I don’t think we should focus on making baal teshuvas. I think we should focus on taking care of the new BT’s that are already in our communities, even after they were married and established a family. Ersht demelz, they need support.
