Attacking an individual's beliefs is pointless. If you want to compel someone to your way of thinking, then you must find common ground and appeal to them first. You need to find out why they feel the way they do and come at them from a compassionate angle.
I've most certainly brought people around to my viewpoint, but it was not through offensively tearing down their views. Most people simply shutdown or get defensive in such a situation, and being an NF I know how extremely sensitive some people can be .
So no, not offensive, but I can be persuasive if it's something I feel is important.
