This article nicely summarizes the frequent douche-bagginess that deaf / hearing-impaired people are facing.
I can confirm that every single point once in a while ruins my days. Interestingly, I find the point “But I find subtitles annoying” very upsetting. It happened to me several times that I was invited to a DVD evening with friends and when I asked for subtitles to be switched on I was facing an hour long discussion about whether or not it is necessary. Seriously, the most disappointing fact is that it is even highly intelligent people fail to get that a hearing loss is not “negotiable”. When I say I need subtitles, then it is a fact and not a matter of convenience.
