I'm aware of postmodernism and I too am a fan of Jordan Peterson. The thing is that there is discrimination against the deaf in the workplace, this is a fact, there's far too many misconceptions about us. I still even get people that insist that I can't be deaf because I can speak for example.
Being a Peterson fan yourself, You should be aware that while there is no real gender pay gap due to discrimination namely among the genders with the rare exception here and there that could be attributed to as such, there's however, a demonstrable fact of discrimination among the disabled.
Including among the deaf even. Many employers feel by and large that hiring a deaf person is too unreasonable because of our accessibility needs, even though many of us from the mainstreamed society can typically lip read. If an employer sees someone with a disability trying to obtain employment, they weigh in whether or not they can provide reasonable accommodations because they do want those tax credits for "removing barriers".
There's also tax credits for employers who hire women and racial minorities and the disabled, however the employer is more apt to hire a deaf woman over a deaf male, on account that the company literally gets a bonus for two things instead of one.
You are aware of these factors yes?
