Do you know why Stephen Hawking doesn't eat vegetables? It's because that would be Cannibalism.
I'm really bothered toward you joke against physically disabled people.
I'm a retard and insensitive, and I mean for vegetarians to eat vegetables.
You should try to sympathize more with people suffering from physical disabilities, so that you understand what they're going through before you make inane comments like that. Empathy is important because it helps us understand how others are feeling so we can respond appropriately to the situation.
You seem very knowledgeable, can you tell me about the purpose of life?
No, I cannot answer that question. I do hope I helped you realize that saying these things really isn't worth offending other people. We should be supportive of people with these disabilities and not put them down.
