Nah, teach your kids to be open minded and accepting individuals. This doesn't make them gay, either. It's not a choice.
(They're wired this way.)
No reason to shelter them and have them be against it.
So much disagreements and hate today it's ridiculous. Gay parents won't influence their children or other children around. If that's the case, then why haven't straight parents influence their children to be straight when they're gay?
