I agree about the drunk routine. I read somewhere that when drunk, your true feelings come out so obviously this guy have always wanted to make fun of deaf people and being sober, he wouldnt dare. With being drunk, he doesnt give a flying f*ck, so he lets his true feelings about deaf people come out. He is an asshole PERIOD!
As for being out with hearing friends and other people making fun of me, I usually act too fast for my hearing friends to take any action. I usually go up to the person and ask them what is their problem and if they are willing to talk it out, then I will explain nicely that it is very rude and disrespectful to do that. If the person refuses to listen and continues to make fun of deaf people, then I just walk away and move away from that person. Not worth getting into a fight about it if the person is not willing to listen.
I dont know how I would feel if my hearing friends took action to defend me. Never had that happen yet.
Besides, like Skyportie said, I dont go to bars that much these days. Getting old and prefer to do things with my husband and kids.
