Sure they will! All you have to do is appeal to their reason, and point out how not acting like a barbarian will give them better returns than making themselves an outcast from other, more civilized folks. Appeal to their greed, if nothing else. That often works...and that's what I mean by self-interest.
With a screenname like yours, I guess I ought not be surprised that you like to argue. :)
Who me????? :^}
What's your excuse?
