I read an interesting passage this week, one that wasn't meant to apply to the abortion argument, but that doesn't change the fact that it applies pretty well to both sides, IMHO:
"In their zeal to protect something precious, people sometimes decide to dig the moat too far out, thinking that it is safer to defend too much than risk defending too little. The result is that they end up trying to defend the indefensible, clinging to an extreme position that is actually vulnerable only because of its exaggeration."
D. Dennett
