Its harder and harder to avoid things you don't want to see or have kids seeing.
Even shows that you wouldn't think would have an agenda drop them in even very subtlety. Just look at HGTV and the DIY channels for example. You think a show about houses and real estate would be at least neutral on the subject not wanting to invite angry backlash.
But no, lets meet our homeowners!!! Oh look its two gay guys, (the Canadian produced stuff is the worst offenders, thank you taxpayers of Canada, yes, most get tax money there, just look in the credits) and at least one of them is flaming!!!! And look, they have expensive taste and like to decorate! Talk about stereotypes!!!
If you took that ratio of gay people you see on TV you would think that gays were a large portion of the general population (less then 1% oops). It seems some times there are as many as married couples on those home shows, and you see them even more then singles even. I don't know if they do it for the drama, as it seems that those shows have more of it, but its something they don't really hit you in the head with it, but its there.
