all women are the same, all men are the same
See, I agree that the stigma is silly and it would be nice if I we could get over it, but I don't think that's an argument against it. Because it isn't actually true. That's like saying all cars are the same, or all tables. They're the same category of thing, but they're not all the same at all, they come in a lot of very different shapes, colours, ages and conditions. The variety of the human body is quite amazing, and actually I think that's a reason why people do sometimes ogle each other a bit - not sexually, just out of curiosity at the "otherness" of people.
