In this question, why was this answer deleted? The answer is a question intended to demonstrate reasoning -- the question asked if Eisav was Jewish, using Yaakov as an example as Jewish by birth, and the answer tried to show the flaw in that reasoning. (Answer text: If Yaakov was Jewish, was it by birth or by accepting God and torah? If the latter, this has no bearing on Eisav.) The answer was deleted as off-topic and I'm trying to understand the problem.
(Sorry if Meta isn't the right place to ask this either. I couldn't leave a comment on the deleted answer.)
