@TerryMiller, Warning points are like demerits; you get them for violation of the site's rules. Example: Tommy45 calls JoeBob38 an ignorant ugly, idiot because JoeBob38 won't agree with him.
First Offense: Probably just get a Reminder - no points, just a reminder that that type of conduct is against the rules.
Then Tommy45 calls another member, Donk211, a blithering, stupid, fatherless fool, because Donk211 likes Glocks over the 1911.
Second Offense: Now Tommy45 gets a Warning. That means he is given negative points, usually just 1 to start.
Third Offense: It appears that Tommy45 is a slow learner as he insists on being rude and calls other members foul names at every chance. He might get 2 points this time, and then the cycle continues until suddenly, the software gives a 1- 3 day ban for his bad behavior. When he comes back, he is boiling with anger and calls every body all kinds of bad names and uses racist terms and derogatory language about another member's mother. Points pile up: When he hits a certain number in a certain period of time, the software that runs the joint will put a strike through on his user name and he will be outta here on a permanent basis.
Would the labeling of another member a "lib" be against the rules?
I mean, if a guy admits he's a lib, that'd be ok, but calling a guy a lib just because he refuses your advances, or because you're too stupid to understand the meanings of words is pretty dang sorry.
Personally I wouldn't ban anyone or put anyone on ignore.
