No, it only dignifies it in his own mind. What it does is make the board more enjoyable for the rest of us, and makes it a friendlier place for newbies. So this forum is not the ultimate free speech, anything goes, smackdown fest it could be. So what? I've seen some of those boards, and while they may be fun once in a while as a novelty, they grow tiresome fast if you want talk about something honestly or in depth.
Debate IS supposed to be a clash of ideas - hence adversarial in nature. Synthesis can NEVER occur if one does not allow thesis to to collide with anit-thesis.
Besides, your idea of forum 'utopia' is nothing more than a tyranny of like-minds - a stagnant swamp where only disgusting and cowardly creatures would deign to reside.
