I disagree with folks all the time.
When a dumb person like you or clv or tehteh argues with irrelevant or incorrect points, the argument continues. I let them know they are stupid.
When I argue with an intelligent person like nsacpi, harry, thewpk, jpx, sometimes smoot, mistake7 or matt, and a few others, they either change my mind, or we simply disagree.
I'm sorry you can't see the difference between calling a person dumb, and using homophobic or bigoted insults. I know it's OK where you live, but the rest of the world can easily see the distinction.
