This is not the way to protect your children.
You don't want them to have it, see it, hear it, feel it, like it?
Then get your nose out of whatever the hell it is you're doing that doesn't include taking care of your kids. Spend the time with your kids. Talk to them. Teach them. And stay open minded anyway. Get active in their lives instead of bitching about what other people are doing.
The government is not your babysitter, nor should it be your moral guardian. That's your own damn job.
Start doing it.
