Don't get me wrong, this does not mean we need to "flame" each other as AnkleBiter says. Challenging ideas and exchanging information is a very healthy way to communicate. Maybe I am wrong, I mean, I see a lot of post that show scars from previous forum massacres, to which there is an intense aversion to repeating. But debate has been used for centuries as a proven method of finding answers and expanding knowledge, as long as people can avoid the "Dumb, ignorant, n00b, stupid and moron" comments, and respect each other, there should be no problem.
I have spent a lot of time in college and the military as a psych tech so this sort of banter is harmless to me. Trust me, I get that not everyone can get on these forums and have their beliefs challenged and not take it personally. To those people I say, don't sweat it, this is common practice for the real world, take this opportunity now to practice having an opinion and don't be afraid to adjust it as new points of view are presented. And don't be nervous; people want to hear opinions, this is why we listen to talk radio or read the editorials. It is stimulating to hear a point of view and forces us to think. So the next time you hear someone give an opinion, thank them, and return the favor by sharing yours.
