There is no reason to hide one's hearing loss.
Yeah, sometimes some hearing people can be real jerks and and act like total @sshats. And when they do, everyone else sees them for what they are.
I believe most hearing people in today's age are very sensitive to people with hearing loss. When I am at work, I wear a name tag which states "hearing impaired". When people speak too softly or move their heads around so I can't speachread, I stop them and point to the name tag. About 99% of the time, the person will attempt to speak directly and enunicate more clearly. Also have had several hearies try to sign.
Once, a woman simply looked at me in the eye and said, "Oh, I don't have time for this. You need to start hearing better." A hearie overheard what she said and he said to her in a very loud voice, "Wow, lady. You're a real @asshole, you know that?" She left quickly and everyone around started talking about how rude she was.
