I find this topic fascinating, and, weirdly for someone who would be a contender for "angry feminist of the year" I have actually changed my view on certain types of pole dancing.
Gymnastics isnt a sexualised performance art. Its a sport.
Actually I disagree, but also agree (ahh confusing!)
I do think gymnastics in some ways and forms actually is sexualised performance art/dance.....like ballet can be.
I'm thinking mainly of the floor stuff, where the men's pieces are all acrobatics, but the womens involve fucking ribbons and balls and pointed toes, with provactive poses and tiny leotards.
BUT.......
"proper" pole dancing I think has more in comparison with those "street" gym things.... I can't for the life of me remember what it's called...not parcourt...that's the running around thing! 
You know, all those muscle bound guys holding themselves sideways off of lamp posts?
My brothers girlfriend is who changed my mind.
She does pole dancing, as a competitive thing.
I have seen her routines, there is literally nothing, and I mean nothing in what she does that is remotely comparable to sleazy club dancing.
And btw (not that this should matter) she is a proper "hippy" type, who teaches yoga and is a very angry feminist type to boot.
She just happens to be very into gymnastic type things.
No flicking hair, no sexy gyrating moves, just sheer gymnastic strength, and amazing balance.
It is literally identical in moves and style to the thing I mentioned above, with the topless guys hanging off lamp posts.
I actually think it's really fucking sexist to basically assume it's just for sexiness.
You don't look at those guys on lamp posts and think it's about sex, you immediately assume it's about strength.
I think assuming all women pole dance (knowing what I know about the actual sport side of it) just for the male attention is really fucking shit. But I wan't to make it clear I AM NOT talking about clubs, I am talking about the sport side of it.
My feelings on pole dancing in a club context still stand.
