foureleven, you haven't even read your own link right!
Pole dancing beginner classes (for women) - they lead in with exercise - whether you haven't done any for years, or are a fitness fanatic. They then go on to talk about getting fit and confidence boosting. At the end of the course they perform 'tricks and poses'. So - exactly the same as the mixed classes, where you will see, (if you bother to read your own links properly), that the men and women learn to pole dance - not just poses and tricks that require strength, and fitness, but the dance moves that link them all together.
They also offer separate courses in burlesque, sensual dance, pole choreography and musical theatre.
Sheesh, if you can't even be arsed to properly read the material that you cite to try to make your own case...
FWIW, I've read Ariel Levy as well, and whilst I agree with her on somethings, I don't agree with her on others - and vis a vis the popularity of pole dancing classes, I know she has got it wrong.
It strikes me that no matter what a woman says to you about her reasons for doing something that she enjoys and you disapprove of, you think you are right and she is wrong and are not willing to entertain the fact that she might have thought things through, looked at the big picture and come to a different, but still entirely reasonable conclusion to you.
You know best, or think you do. You seem to want to save her from herself, or at the very least to pour disapproval on her for making her own adult choices about her body, her use of her time and money, and to think less of her for having the temerity to choose to do something that may or may not be sexual or playful because she enjoys it.
You aren't alone in this - others, loftily convinced that the woman pole dancing is making a frightful mistake, being tacky, slutty or complicit in the oppression of herself, her daughters and women everywhere have said it too.
How incredibly patronising and sexist that strikes me as being.
