That's funny... I'm not finding it personally insulting as I knew I would likely get a negative response as I've been on this forum for some time just didn't register. I am judging it's effectiveness by my sons speech and language skills, his grades, and his level of social comfort. He is able to move between both worlds, as he is a part of both. I know it is effective because his language skills in English surpass his age. I know it is effective because he is happy and confident in who he is, and can clearly express his wants and needs in sign and voice.
If I came in here saying that he is Oral and doesn't need any sign, I could completely understand people having an adverse reaction to it. The fact is that we do sign, and I do know some ASL. I have mastered SEE, and my next step is mastering ASL. I wanted my son to have access to language, he got it.
