I'm sure you have seen my post about repeatedly derailing topics, as well.
He is clearly a racist from his repeated posts about the people of Macedonia and he is a sniveling whiny bitch in that he keeps posting about the links I provide when he can google the topic if he hates the source and/or the people of Macedonia so much.
He refuses to discuss any topic.
His posts are only to attack the source, in a racist rant.
