@coluber2001,
Just because an artist has a sincere or earnest message behind a given work of art, doesn't mean that work of art is more valuable than the sum of its aesthetic, cultural parts.
Anybody can write a well meaning, thoughtful, activistic song criticizing society, political structures, etc.... Well meaning messages automatically don't make it a good or even a listenable song.
Art for the sake of shock value? Simply on those merits? Doesn't always work. I doubt too many 'average' museum goers would give this site installation much thought ... X number of days after they visit the museum and relieve themselves into the solid gold toilet... other than ... "I wish I had a solid gold toilet" when they themselves are sitting on their own home or work toilet ... doing their personal business.
