If they aren't gay then they aren't gay. If it's with the intention of "making things gay to increase awareness of how gays are okay" then I'm not sure this is the way to go about it. If it's being shown to accepting families then they gain nothing. If it's being shown to less accepting families, they will tell their kids to turn off the show that has the homosexuals on it. Sadly. This would mean that young kids watch something other than Sesame Street, missing out on the values that exist within it, which would probably have made them more accepting of homosexuality anyway as they grew up... well, it'd help them, I guess, anyway. Hopefully.

But yeah, an interesting idea with good intentions I'm sure, but possibly not the best place to kick it all off. And I agree with the "if they aren't gay, they aren't gay" thing, too. I think it would be better with new characters rather than old ones.
