The point is there if he were less dressed (and there have been plenty of male performers that have and done gyrations) and doing some of that kind of stuff, this thread nor the stories about it would be happening.
This isn't anything new. People seem to forget Madonna and her 'erotica' album. Does it matter if the person has talent?
What's interesting to me is this did exactly what was expected, people talking about it. She really is not that great of a singer or a dancer, heck I don't even think she looks all that, but yet here we are talking about Miley Cyrus. Nobody is going to care in a week.
So you are arguing here that no matter what a man does on stage, nobody would discuss it? Sucks to be a male performer, if that is true.
