no offense, but i'm wondering if you should play a character like this if you're questioning stuff like this. are you new to dwrp in general? i can understand this more if so, but...

deaf characters can read text/ask people to use text, or use a subtitle function on the comm which more than likely exists. blind characters can use screen readers. mute characters can just text forever.

"ableist" stuff to avoid is, again, common sense like not making the blind character trip over everything lol how clumsy!! they need help with everything! etc shit like that. pretty basic, anon.
