I support the removal of Trolls and the like when they do the following:
1)Openly support the killing of our Troops
2)Openly support the overthrowing of our government. (If ya don't like something, get off your butt and vote!)
3)Openly give aid and comfort to our enemies
4)Openly support the killing of our President or any government officials.
There is nothing wrong with dissent. I actually enjoy the debates when it doesn't come down to name calling. Unfortunately, it usually does.
Even absent name-calling, tedious folks who don't know the difference between opinion and reasoned argument are a waste of time.
As are those whose sole ability is criticism without the slightest clue as to any substitute real solutions.
