Popa,
Maybe I am hopelessly naive, or an eternal optimist, but I read a few of his post and they sound like kiruv talk to me. There is a slight difference in tone in that it seems like when he says “many find _______ troubling today” he is trying to imply that he too finds ________ troubling.
But even if this were so, and I finds some aspect of halacha troubling, I don’t see why that makes him and his school apikorsim. Part of yiddishkeit is keeping the mitzvos even when you don’t understand them, being mevatel your daas to that of HKB”H.
