No doubt. The assertion that Star Trek hasn't used sexy, scantily clad ladies to sell their brand is beyond absurd.
You are in serious, serious denial if you believe otherwise.
I didn't see anyone denying it but just because it was like that in the 1960's doesn't mean it has to be like that today. Compare sexism with racism...none of the "minority races" got as much screen time or were major characters, does that mean modern Trek should be the same?
