It's not that it makes you not post, but the majority of the time it isn't necessary. Most of the time, approaching a post from the position of, "That's wrong, and here's why..." is just as effective as, "ZOMG, you're such an idiot, and here's why..." Telling someone they're dumb is not necessary. Effectively break down their argument and they'll probably realize their post was dumb on their own. http://3.bp.blogspot.com/_ICXs0E2rWLo/TUP8iLgu98I/AAAAAAAABKQ/v67P0pprYJg/s1600/Antoine-Dodson-Dumb.gif
