Why did Helen Keller's dog kill itself? You'd kill yourself too if you were called "WEAAAGHURRGHHAAA!"
That's horrible! Why would you make that kind of disgusting joke about a disabled person?
I'm sorry, I thought I could /ignore you and talk with other people who like to bully disabled people.
You should put yourself in the position of a physically disabled person before making an ignorant comment about them. Empathy is important because it helps us understand how others are feeling so we can respond appropriately to the situation.
Who says I'm not a disabled person? Maybe I'm blind and can't check the chat.
Joking and pretending to be disabled isn't a get-out-of-jail-free ticket to insult them and do bad things. Being disabled is hard, and you being flippant and rude about it is cruel to anyone who struggles with it. They contribute to the world and deserve respect just like everyone else.
