I believe this is what that guy meant to say:
It's really pathetic that a guy with Parkinson's won't get up off of his lazy ass and get a job! You don't see Muhammed Ali or Michael J Fox asking for handouts, do you? This guy should just take responsibility for his disease and suck it up. No one forced him to get Parkinson's. It's not our fault that he can't walk.
If we give him health care, what's next? Government health care for the elderly? It's just un-American. Next thing you know, they'll be getting rid of Medicare and replacing it with government health insurance for the old. That will be the end of the America as we know it.
But just to show you that it's not that I'm selfish, watch me take a couple bucks out of my wallet and throw it in this sick man's face. There! See? I'm not a hard-hearted bastard after all, am I?
