Had this conversation with someone who chose to no longer be at my table after meeting a blind NPC
Another player who was at the table during the incident sent me this meme after the problem player in question (they had a history) left the group chat.
Felt like sharing it here because I'm sure more people should keep this kind of thing in mind.
I've seen them somewhat often in RPGs and related material. There's those who are blind, frail, deaf, weak or lacking a skill to do something necessary. Even Basic D&D had notable penalties for rolling INT 3-5, being illiterate to start with.
NPCs in fantasy settings still have hinderances, and they're expected. Maybe they can be neutralized by healing magic in D&D, or there may be equipment that works around them. The wrong part is shutting down the concept, as that's contempt for the weak (technically a symptom of fascism.)
While Nazi-Germany was infamous for 'euthananizing' disabled people, it is sadly not a principle reserved for the right extreme.
Luckily most don't go as far as right out killing the weak. But sadly there is almost always a splinter group in any political or ideological orientation that shows contempt for the weak.
