Yet. You left out the word yet. So far we have seen every fetish under the sun become more and more acceptable in the disgusting world of porn that is now the number 1 industry in this nation. And you don't see a slope?
The greatest harm to the economy has come from banks and board rooms, not tatoos and tutus.
Porn is nowhere close to the #1 US industry and piercings play no part in eroding the GNP. Genetic makeup - or even personality development in childhood, is not a "lifestyle choice". Mind your 9th commandment, Bonzo.
