I was really in love heads over heels in love with Torah in the most powerful way possible. But it was like getting a bucket of ice cold water poured over my head to realize how corrupt and dishonest and unholy and unclean the religious world is. The world that claims to be keeping the Torah is not the same as the people that actually keep the Torah.
If the authentic Lithuanian yeshivas are overly cautious about whom they let in their doors it is because they have been burnt too many times and thus err on the side of caution. [Of course the trouble is they end up most often throwing out the sincere people and leaving the hypocrites that have rich parents. Still I think it is obvious that the religious world needs a thorough Chametz cleaning. Throw out every single last bit of chametz leaven is my recommendation.
