using the word retarded to describe anything is foolish.
It is an insult to great art that you include Mendelssohn in that list. I'd like to see a realistic criticism of his works beyond him being ein Jude by birth.
I completely disagree. If you know the etymology of the word, it's the perfect description.
Honestly, I think onan is just making fun of contemporary artists with a jewish background.
perhaps its the PC douchebag within me, but i see "retarded" as being a very juvenile and immature way of describing things.
