Patranus,
The problem is not the few that are the bad examples of the many. You can cherry pick a drug using wife beater as an example of why food stamps are bad, OR you can look to the majority of widowed, divorced, or simply underemployed individuals that use them to get the food they need to LIVE.
The key here is not to categorize EVERYONE. Humans are so good at bad type casting. We relate to a few handfulls of relatives and friends, and the rest are "them". Also, somehow people with a differing opinion have to be objected to 100%. Like somehow agreeing with them on something like Education or Health Insurance means that you will be in lock step with every other topic on the planet.
Nice fantasy that the Tea Party is now finding out is root-and-core false.
The only thing that we should realize is that 80% of the people out there are STUPID. Good, bad, ugly, does not matter. Hell, even "smart" people can be incredibly dense when it comes to things like socio-economic issues on a macro/global scale.
Once you realize that, then it is easier to see why we get this. We elect pretty people that speek lots of nice words as our leaders as they are paid by corporations to make all those nice commercials that make us like their niceness even more. And when someone tries to do something different, any closet they have is opened, whether it is theirs or not actually, in order to somehow discount what is being said by mere association rather than substance.
Bottom line? 90% of the protesters are stupid, but so are 90% of the ones objecting to it. They key is to find out what is really f'd up and FIX IT rather than yelling for someone else to do it.
