Let's start with the premises.
First: this is private property. Like everyone but the proprietors (Viratas and I), you're a guest here.
Second: we created this place to allow open dialogue between members of the wrestling community. This is different than free speech, though open dialogue requires a good measure of it. We allow debate on virtually any topic, and let people take any position in a debate. We do not allow any behavior whatsoever.
The main reason we do not enforce much is that attempting to hold a community to a higher standard of conduct than it wishes to maintain is probably futile... or, at least, a great deal more work than we're willing to put into it. As a measure of our permissiveness: in nearly five years, we have banned exactly one person. If the measuring stick for this was whether people rubbed me the wrong way, rest assured that the count would be a great deal higher.
That said, when the community actually wants civil dialogue (as it should more often), we're going to make sure it's possible.
Now, in case you were wondering (and you were not) why posting political pictures in the Pretty Ladies thread was unacceptable: because by doing so, you were attempting to disrupt a "conversation", and irritate people whom you dislike.
Likewise, when someone requests an honest dialogue with people he disagrees with, and they respond in kind, chiming in with sarcastic, misspelled nonsense is an obvious attempt to disrupt the dialogue.
As for where the line is: I'm not going to draw one, so that you or anyone else can skirt the other side of it, or play a game of drawing comparisons. Since you have no right to speak here, we don't owe you due process. If you see this as arbitrary, that's your prerogative; ours is to be as arbitrary, capricious, and tyrannical as we please. If this bothers you greatly, feel free to start a forum with a litigation process.
Now, I suspect that you know how to be civil. If you choose to be, and wish to actually talk to the people here, it's unlikely that you'll ever have to worry about where the line is. If not, don't expect further warnings, or an explanation as to why you're no longer here.
