Art and irony would disintegrate the personality, kitsch makes it whole.
Kitsch is all that the modern world makes that's not modern, which is most of it.
Art daunts us with its cold exacting dullness, kitsch gratifies us (with cosy democratic largesse).
Kitsch makes things that are pretty as representations, but ugly as art, modern artists made things that are ugly as representations but beautiful as art.
Artists now decline to go to bed with beauty, fearing they'll wake up with kitsch.
