I don't think you effectively critiqued yakshaving by repeating what he said about the commentating art community. Their opinions are worth no more than his, my, or your half-arsed opinions. You haven't defended them when he's speaking against pretentiousness.
Art is art, and it doesn't need an adhoc recital of catch phrases and in-words performed by those gathered around. In saying "You just don't understand", you gilt no dirt.
There's no need for a bait and switch. Yakshaving didn't criticise the art, he criticised the chatter, which is just a gussied up version of "I like the colour" and "The way it creaks in the breeze gives me the heebie-jeebies".
Its like a party after a hanging, and regardless of whether it is a painting, or an outlaw, there's something uncomfortable and unnatural about people gathering around to nod their heads in satisfaction.
