My comment: It is such a shame that employers discriminate. Although many do it subconsciously, without realizing it, plenty of others intentionally make an unfair decision based on factors people can’t change like race or age. Also anything from the hiring process to the rate at which one is promoted or not promoted plays into whether the person is attractive, capable, etc. I think you are right in that we tend to overlook ableism. Unfortunately, the most qualified candidate isn’t always hired.
