I've got nothing against missionaries, but I come from the school of thought that proclaims - I belive in freedom of expresson, provided you express what you want away from MY general direction.
The BEST quote ever said to missionaries:
"Your God wants you to waste your life- your most precious gift- by trying to enslave others with your views. Dont you think God wants us to be happy, make our own descisions and our own paths? I do. I beleive in a fair, good, kind God. So get the ???? off my doorstep before I make a descision that involves you, me, a shotgun and God almighty himself."
