Why do you think he should be banned, just because his logic overpowers yours and you don't have anything else to defend with but instead bicker with pathetic post demanding him to be banned? 
I've had few round ups with him on chat and thread, the moment I found some of his replies logical, I quit. Sometimes, it's easier and wiser to quit off of arguments than to get involved into and prove yourself more of who you are, I dunno.
If you think he's acting smart, you act smart and show him you are smarter than him, why "all this kolavari"?
Let's live in peace, brothers :D Let there be healthy discussions, as long as admin want there to have one :D 
much love
