Why are girls "topless" but boys are "bare chested" when shirtless?

I agree its sexist and I think women should be able to be barechested as well .I am a nudist and to be honest the naked body shouldn't be covered its an amazing thing and its just a narrow minded society that expects us to cover up .

That is changing in some places. In Toronto women are allowed to be topless wherever men are allowed. Would you be interested?

Is an obvious gender discrimination but it's socialy accepted
