It kind of sounds like you're arguing against artistic freedom within big companies, though. As in, weird little shops can do "sexy" publications. However, once a company is "big" it "should make the decision that they aren't going to sexualise women in comics for no good reason"?

But why should this depend on the size of the company? Either companies should be able to sell a product (it is acceptable to the community, culture, standards, etc), or else they should not.
