ive played with a fair few people wit disabilities over the course of my playtime.
i was once in a pug that was being lead by someone who had a deaf irl friend in the raid, he refused to say who it was to protect them but mentioned hwo he had simply set up macros that would whisper his friend when he had to do something and tbh, there was no way to tell who it was because he was playing so well that even sherlock holmes wouldnt figure it out.
i also played with someone who broke their hand, in just over a week they managed to re teach themsef to play with just 1 hand and a few macros.
he even managed to get an increase in dps once his hand was healed because he could play with either hand and pay mroe attention to movement etc.
i think that anyone who would discriminate for a disability is just worried that theyll be outperformed and due to their smaller brain, feel innadequate.
disabilitys have almost 0 effect on playing alot of games.
the inability to use vent can be a hindrance, but its not somethign that cant be worked around.
sure a paraplegic may take longer bathroom breaks if their computer is a distance from the toilet but whats an extra couple of minutes?
