Yes, I have visited oral schools. Never liked what I saw. Too many "can u say that again" or "I can't understand you's" in the lesson. Not for me. No thank u.
Also, I don't understand what's wrong with children having both. Seems like it is not acceptable to you which is fine. Then, there's no need for us to continue to justify our views.
I was answering Daredevel's questions not trying to pick another fight with you.
Thanks
