Its in how it is done, Jar. This forum is not the same type of competitive atmosphere as your old boarding school porch debates. Logic and common sense are not the only game in town here. We seek to present the rational as well as the irrational. The mundane and the mystical.
Of course, all viewpoints should be supported in some way shape or form, if possible. Often, however, Faith/Belief views are by nature unsupportable except in scriptural context.(itself a debate)
Respect for the other individual is important---even if you personally think they are a conman, a delusional cultist, or a brainwashed teenager.
If, on the other hand, they become frustrated and don't respond to your (polite) constructive argument, chances are they will be the first ones to call
you a name. In that case, we all shall see it publically and if a moderator catches it, it will be dealt with.
You have every right to ask someone to present their evidence. You ask me all the time, and occasionally I have some...most of the time I do not. Such is the nature of belief.
Buz has publically apologized for calling you a liar. Many creationists are frustrated with you because you dont ascribe to dogma. You test all truth claims against logic, reason, and reality.
You don't have to win every argument in order to have the respect and attention of others.
The audience of lurkers and viewers knows full well the points and counterpoints.
