So you hate someone based on their looks--not their personality, not their beliefs, just their appearance.
What's your medical degree in that you're knowledge of the human body is so great you can tell just by looking at someone that they are unhealthy--to the extent that you call abuse?
I assume you feel the same way about someone who was speeding and got into a car accident because they could have avoided it right?
So don't take the bus, drive yourself, or walk. Do you feel the same hatred when you have to sit next to someone who is healthy but has broad shoulders? I somehow doubt you feel the same way as if you had to sit next to some "fatass".
I've never sat next to someone fit that smells bad... [rolleyes]
How about posting up a picture of yourself shirtless and letting the internet pick you apart based solely upon your looks--I'm guessing that plenty of people can find flaws in your appearance.
The point I'm trying to get across is that we're all human--we're all different, discriminating against someone based solely on their appearance is wrong. There is no difference in the act of calling someone a fatass as calling someone a ******, you're making a decision about the person's quality based on their appearance regardless of "if they can help it" or not.
