Jesus said that the Christian position is indefensible? I agree as to the supernatural stuff, the antisemitism, the homophobia, the religious intolerance, the slave-owning, the denigration of women, and so on, but I didn't know he was out loud about it.
Where did he say that?
Anyway, since you say your 'proof' is 'irrefutable', well, he wants you to pour it on the whole world, skeptics especially, no?
Of course, if it were thoroughly refutable, if it's one of those believing-is-seeing things, well yes, it'd be dumb to go public with that.
