I think I already replied to this matter in someone else's blog, but I'll say my piece here, too...
First, I'm Christian, and I can see through the mire of the "gay" cartoon crap...at least I hope that is what their intentions are. I believe that homosexuality is sin, because my Bible says it is. My Bible also says that *I* as a heterosexual, sin every day as well...so blah about that. I'm hoping these groups' intentions are to protect our kids. As a teacher, I'm glad that our textbooks are becoming more diverse. Ten years ago there weren't hardly any minority groups or people with disabilities relfected in the pages of those books, and today there are, and that's AWESOME! I want my first graders to see "oh...that kid in a wheelchair can add, too." or "Oh...that Asian kid knows all about time!" or something, you know? But if I were a parent, I think I'd have a hard time knowing that my child was having seeing a homosexual-led "family" in the pages of those books. I'm not saying that I want my kids to be clueless like I was for a long time about homosexuality and gays and lesbians, but I'd rather that it was something we talked about as a family versus having a teacher having to answer questions about it in the classroom, you know?
Does that make sense?
On the other hand...they're freakin imaginary characters that just cannot be homosexual. A sponge that lives on the bottom of the sea? A giant purple dinosaur? Give me a break. There are millions of people on the other side of the world that need time and money right now. Homosexual animated, imaginary characters should be the least of our worries. Kids are just watching the shows for fun...they're not thinking about how Barney is gay or how Bob is gay, you know? They just don't really care about those things unless mom and dad shove it down their throats.
PS...Christians out there....we're called to love sinners EVERYWHERE! No matter what the sin "committed," you know? We do bad things every day too...
