I hope not. The Deaf culture is like any culture. You have left, right and center. It really depends on many factors that determine how a person treats other humans. If parents choose CIs' for their children the last thing they should have to worry about is rejection or that their child will be seen be seen as a freak or cyborg or some nonsense. Unfortunately as you have witnessed, it does happen.
These are children we are discussing. Babies! I just don't understand these views. I personally feel this type of comments is a reflection on how they feel about others not just CI children. So those types of comments are not acceptable here or anywhere.
