Re: Why is it sexist
"If women what to make their money that way why is it sexist?"
It's not so much the nudity that's sexist as the work allocation. If naked cleaning (ironing, cooking* etc...) ladies was considered sexist, the answer is to provide naked cleaners of whatever gender. And if they want to expand their service to gardening, they can provide naked gardeners of whatever gender. Having naked cleaning ladies (but no male cleaners), and nakes male (but not female) gardeners is sexist.
Otherwise I agree that as long as people do it willingly, are not abused on the job and are fairly compensated, they should be free to choose whatever they do.
*PS I would have though naked cooking rather unhygienic, no?
