What PG is describing sounds like one of those "hot or not" apps, where people make an instant judgment based solely on physical characteristics (and sexual possibilities). I don't think you need a pageant for that, the internet has enough of it already.
While I am in favour of your call for more diversity in the contest, I wouldn't restrict that to just physical characteristics.
On Mark's point, "Miss Relationship" could be a new contest, but I fear it would not be inherently televisable in the same way.
It would not be fair to have homosexual men judging, because that will not tell us what straight men find attractive.
OK but neither will any given set of judges, as people have vastly different preferences. You only could get some sort of representative average, but we already know what that is - in your terms, it's the "barbie doll" default.
Anyhow, even if the contest was based only on simple physical characteristics, it should not be only heterosexual men who determine the winner. Anybody can vote, and (possibly) anybody can become a judge.
Actually, how about opening the contest itself up to both genders simultaneously?
This is a common problem with runway models, you can clearly see a lot of them are chosen by gay men.
It's not a problem. Modelling clothes, and turning you on, are two different things that shouldn't be conflated.
gives legitimacy to the continued existence of those who seek experience with many women of different ethnicities just for the sake of it
As opposed to those who do it for a genuine altruistic cause.
