I think people get upset about this not because of the sexual preferences, but because discussions about sexuality are wildly inappropriate for preschoolers, just like suggesting their parents will eventually die. I myself would have a problem if Sesame Street had open discussions of these topics, although I plan to discuss them with my son when I think he's old enough to handle the information. Frankly, think about it - you don't discuss heterosexual relationships with your kids in that context. None of this means I don't support homosexuals in their choice to do what makes them happy, nor would I ask them to hide their choice from my child, but it's still not an appropriate topic for preschool-specific television. Sesame Street clearly agrees with me on that point.
