Sam Z, if you do not want your children to be exposed to the idea that being "gay is cool" then simply don't let them watch movies like that.
That's all.
In order to FULLY "protect" your children from being exposed to those ideas you would either have to isolate them from any media that may go against your beleifs, or Gay characterization would have to be always in a negative light.....which do you choose ?
No one said "being gay is awesome" on television, its taught that "its ok to be gay" and its true.
Being gay is a not a choice. There are gay virgins, being gay only means that you WANT to have sex with those of the same gender, nothing more.
Your kids will not turn gay, no matter how many people tell them to "be" so RELAX.....
