Without reading any responses to the original post first, I think it is a very sad question. It’s not up for debate. Being Jewish is a factual thing: You were either born Jewish (to a jewish mother) or converted halachacilly… If you live a Torah life – is up for questioning… You cannot “decide” to become unJewish. (Based on his actions a person may lose is chelek in Olam Haba, maybe even Olam Hazeh too…) but the fact that he is Jewish – how’s that a question?
