So in other words it's like this...public discourse in a reasonable means is acceptable. But as soon as you turn personal and start calling someone's wife a whore...etc, you have crossed the line. At that point you are breaking forum rules and are subject to the appropriate penalties.
The turbo forums can be some of the most contentious. You ARE free to discuss and even disagree about the information, brands or what have you, but don't cross the lines of decency.
