For me it isn't pride, it's just stating that I haven't particularly kept up. I was never really one to follow the latest fashions but more of a statement than a celebration of my ignorance.
I would also suggest that whilst it is sad to see musicians being ignorant of modern music, there is something sadder when you get older people trying to be "down wiv da kids". My eldest was laughing at me with my wife the other day because I had said I liked an act but wouldn't buy it... his point was "who buys music these days? ANy response from me is simply me being comfortable with myself and where I am at this stage in life.
