I know someone who grew up frum and goes to kiruv events to make friends and learn.
He told me that he is not eligible for the cool fellowships where people go on trips to other countries for a couple hundred dollars if they just learn for X hours for X weeks because he came from a frum household.
At the same time, he told me that he sometimes struggles with keeping Yiddishkeit 100%. Yet since he went to Jewish schools growing up, the donors who pay for the secular Jews to learn overlook him as part of the program.
So from what he told me, it sounds like at kiruv events, he is an outsider insider.
