No. That's not how you were going about it.
It is a fact. I'm not going up to someone and saying YOU ARE MUTILATED. What I'm doing is similar to if I were having a conversation about limbless people with my friend, and then one of us were to say "It sure does suck for people that are mutilated", then an armless man came up and said "WE AREN'T MUTILATED, STOP INSULTING US". It's a term, not an insult.
Why? You can say it like it's a fact, and it's fucking obvious you think you're always right, but it doesn't make it so.
You are wrong. Stop.
