Excellent!
You think this is excellent? As if belittling, trapping, ambushing, or criticizing them will somehow win them over to God?
The only item this list worth considering is #10, but even then I get the impression it is being mentioned almost tongue-in-cheek. As if it would be something you would purposefully do to wound them, rather than SOMETHING YOU SHOULD DO.
My pastor gave a great sermon on this a while back. He basically said that we should be demonstrating why living a Christian life is so fulfilling instead of ATTACKING the lifestyles of others. I think I agree with him.
