The thing that is much scarier is people who outwardly appear relatively normal, but are inwardly snivelling, lying, scheming, gun-grabbing, liberal defecrats. Now they're EVIL.
I saw a story on TV a couple years ago about a pair of twin girls that were conjoined. They shared most major organs, and appeared to have just two legs and two arms. The left twin controlled the left arm & leg, and the one on the right controlled the right side of their shared body. Although at first they looked like one person with two heads, after a while (during interviews & such) I got past the outward appearance and started to think they were a couple of pretty cool kids. They play softball, run, and do just about anything they decide they want to try.
I was amazed at their spirit and that they don't really see themselves as "handicapped", just different.
