I don't have to. I see what you write to other people, like what you said to Line in this thread and your response to Linkalicious with ''good for you kid'' as well as your responses to finti and myself in few other threads.
I disagree with Link all the time, but unlike you we do not go out of our way to patronise or insult - took us time to learn that, but we're over the childish insults. You either are insulting and know no other way, or you do not know how to converse. Either way, your replies hold no credibility with such conduct.
You do not differentiate between attacking an idea someone has put forward and attacking the person themselves.
And you get what you give - do not expect people to give you any kind of respect or credibility to your posts, when you give none to others.
