If you bring forth poorly thought through points of view, I do not have to accept them. I may even think it is stupid and dumb. But I will defend your right to have them.
It is your responsibility to articulate your ideas convincingly. You cannot just shove it down peoples throats. You cannot try to intimidate and slander just because people think your ideas are dumb. That is the line.
Learn to present your case. You should have outgrown childish tantrums by now.
