the way they are marketed is gendered - they are overwhelmingly marketed to women (why is that if they are just a really great way to get fit? surely everyone should be doing it?)
Equestrian equipment is also 'overwhelmingly marketed to women'. The yoga and Pilates classes i used to attend were overwhelimingly populated by women, and the (excellent) instructor's (less excellent) jokes were very 'gendered' (in a toe-curlingly cliched way). It was still great exercise and a lot of fun.
I do believe that the ways football/cricket/rugby/Formula 1 are 'marketed' tend to be gendered too. Does that therefore mean to you that men shouldn't be playing these sports?
the blatant hypocrisy of the denial that there's anything sexual about pole classes
Well... maybe it depends what pole classes you attend. The ones I know of are no more or less 'sexual' than any other form of sport.
because pole is (suspiciously) closely related in form to a sex industry form of entertainment which overwhelmingly exploits women's bodies for men's consumption
Right. Pole dancing is traditionally associated with the sex industry, I think we can all agree on that?
Capoeira was developed by slaves in chains. Does that mean that it shouldn't be practiced? (Or that if you practice Capoeira and are from a Caribbean background you're somehow unwittingly celebrating slavery? I don't fucking think so. Maybe you do.)
Dressage was originally a military discipline, designed so that riders could kill people from horseback. Should it therefore be censored/abandoned because of that?
And how about the history of boxing/pugilism? Do you also think that these are 'victims'' activities and those who are involved in them don't know their own minds or are somehow contributing to the degradation of others?
If you enjoy gymnastics (or if you'd like to and would like to try something similar in a fun, relaxed atmosphere), you might well enjoy pole dancing. (Oh, and no qualified, insured instructor would allow you to wear heels as a beginner. Possibly not ever.)
I'd also like to add that I think generally people feel better about their bodies and themselves if they're physically fit and active. I don't really care whether people get fit through fell running, aerobics (very 80s that - sexualised by Olivia Newton John, so should that go down the dunny too?), circuit training or dancing (pole dancing, salsa, belly dancing, street dancing, ballet - love 'em all). If people want to add a few tassles and have a laugh with that, let 'em.
