Debates and arguments are generally disdained - though many participate in them (often inadvertently). If people could keep it to a dialogue - a courteous exchange - rather than a "debate" or an argument/feud, it wouldn't be such a bad idea for edification. Apologetics is essential IMO, but unfortunately, "you can't cut off a man's nose and then hand him a rose to smell", which is what is bound to be attempted in a debates forum.
