I consider it a fair assessment that a lot of idiots are fat because they have idiotic diets. This IN NO WAY IMPLIES THE CONVERSE: Someone who is large or overweight is of course NOT automatically an idiot. Unfortunately, that needs to be stated when it should be obvious but some people automatically apply the converse. I'm talking about fat due to bad food, beverage, and exercise choices, which in the case of the Astroturf Mob shouldn't be shocking - they also opt to watch FOX.
Perhaps I haven't seen that many pictures or clips compared to most people - I don't watch TV. Still, of what I've seen online and in print, there are a lot of screaming fat people bitching about health care. How long before one has a heart attack during a town meeting?
If you haven't seen Rachael Maddow's segment on who is behind the Astroturf Mobs, you need to watch it. The so called "grass roots" organizations are all operated by rich GOP operatives and industry interests (is there a difference)? This is true investigative journalism - something sadly rare these days -
