I teach my children it is okay to say racial slurs and I even encourage it.
Why do you teach them it is okay to say racial slurs?
I want them to learn to hate other races.
It's terrible that you are teaching your children to be racist. You should be improving race relations by teaching your children to be tolerant of all races.
Race won't matter when I'm dead. I can teach my kids to hate others it will go beyond me years.
You will make life hard for others including your kids by spreading this.  A big part of raising kids is making sure that they are ready for the real world and making them racist hinders that.
