Blessing? By blessing if you mean a form of reproduction that results in parents not fully committed to something they are not ready for? I'd say that abortions should be allowed, otherwise you have dis-function for not only the child, but the people that weren't prepared to raise a child as well.
Liberty is based on minding your own business and not trying to force others into conformity. I sure hope the liberty movement doesn't turn into a "moral" hell hole like the other two parties.
