The strippers thing is more complex, and we could start a new debate with that one, but in general terms, at least the strippers and the audience know what their role is and what they are attending.
There's a whole other debate about the motivations for women to strip (and maybe for some men to strip too), and the imbalance between the sexes that increases the likelihood of a woman to choose that path from lack of viable alternative ways to make money. But that's a huge debate!
In F1, we expect motorsport, not glamour girls. In the past, the two have gone hand in hand, because we used to associate success with wealth and beauty. We are (slowly) trying to breaks the chains of that dangerous myth.
I like sex, I like women, I like a nice figure (which comes in a lot different guises), I just don't need it in the middle of F1, or a boxing match, or used to try and sell me something. I want a woman to like me, not because she's paid to pretend to.
