I hear you, but I don't think it is a matter of "knowing" rather a matter of "caring". I think he knows and doesn't care, and in fact gets a rise every time someone responds to his posts. Those actually make me laugh more than his actual posts because trying to reason with him is like arguing with a five year old. Funny to watch.
For me I like the whole So Cal, vegan taco, Nancy car riding, NY Yankee ballcap, Planet Hollywood jacket, Nike hoodie etc. references. I know many here don't but at least he does you the kindness of registering so one can always place a block on him if they choose. I am more bothered by specific anons that make it so I had to block them all.
