I am hearing with profoundly deaf son. Most of it is simply ignorance. But it is unfortunate that there are some people out there who are so insecure that they must make fun of others to make themselves feel better than. Deaf people are an easy target, those type of weak hearing people think, because they think the deaf can't understand what is being said, or that they are being made fun of. If they knew that the deaf person could understnad them, they would not act that way because they are just chicken sh**. They won't attack people that they know can fight back.
This is the same type of person that beats up on little kids, or becomes a wife beater, or bullies the smallest child in the class. They always go for what they think is the weakest target.
On one hand, you have to feel sorry for them because they are so insecure and have such low self esteem. On the other hand, you just want to whip their ass and give them a taste of their own treatment.
