"If you don't want an abortion, don't have one. Teach your children it's wrong."
If you don't want murder, don't commit it. Teach your children that it's wrong. Yeah, that'll help...
I hate the direction our country is headed culturally. Our kids don't own video games, see PG-13 movies (minor exceptions--and they are 13) or MTV. We explain why we don't approve of these things.
The point is, by teaching our kids, we can fight against some of the sewer debris all around us. Even while abortion is legal if you are against it, tell them why. I hate smoking, but think it should be legal (though maybe not within 20 feet of me!) and I tell my kids why it's wrong.
