My only idea is trying to provide a better example. Unfortunately that's all I have and while I think I make an impact on my own community, because I usually don't see these players again, I don't know whether or not this worked.

However as a note, it seems you and I have run into highly different people as while I do get those rude ones(one very bad memory of seph normal), they seem to be few and far between. That's not to say that the problem doesn't exist as I do believe it's there, I just must have had a run of good luck. If you come up with any ideas, I'll see how well they work within the Mateus community and report back.
