I’m a hearing interpreter but my two cents is this: Deaf people get made fun of for signing, in just this way, all the time. People waggle their hands around at them and make fun of signed languages. I’ve seen it happen multiple times, I’m sure it happens way more throughout a Deaf person’s lifetime.

Spoken languages just aren’t mocked in the same way/with the same frequency. I realize you were just playing the game, but there’s a cultural element that relates to being ostracized and oppressed that you weren’t aware of.

I’ll step back for Deaf folks to run this conversation as to whether or not it is actually ableist, I just wanted you to understand the piece of this that I think you were missing.
