Why do so many people (apparently) on this site exist only to bring negativity here?

Its definitely relates to psychology. They feel inadequate and have some self esteem issues. They are no different online as they are in public and types like that usually stick together with like minded folks or their mates have to block others as some sort of alliance to their mate. You have to feel sorry for them. It is a sign of a weak character where they cannot handle or are strong enough to handle criticism. In their minds, this warrants their actions and words. Weak people that have to block others because reasonable people tend to be a threat to their persona. Oft times, educated people make them feel small. This rather than, learning from others willing to teach. Its a loss really for them. In some ways, I think, they are to be appreciated and not just because they make reasonable people feel better about themselves, superior(?) and in not being like the trolls, but because, the trolls say things that others only would think privately. Theres this sort of freedom to act and say things that some people would never dare to say outwardly. I bet they don't say it in real world public unless with other footie hooligan types. Guess that I shouldn't stereotype but I use it as an example based on personal experience. But ya got to love em because trolls are people too and not take it personality if you are blocked. Yesterday, I did notice the hypocrisy in "N" question. Actually, this guy and mates were the very first in my years of posting that I've been blocked. Found it interesting and in an odd way a compliment towards me.
