We work with these people, they are our neighbors. They donate money to the musea and other non-for-profits that promote this "art." They do not discuss such matters with their children at the dinner table; the family hour is hommage to television.
For about three decades now, my friends, co-workers, and neighbors all think that this voice must be heard. Do not so hastily look down at these "artists." I do not know whose stupidity we should lament.
I've never seen "musea" as the plural of "museum" before.
