Here's the actual Pew Study. Surprise! The purpose and findings of the study are far different from what the right-wing blogs are parsing. But then I find conservatives usually just believe what they are told the liberals tend to want to see the raw data and decide themselves. (I made that last part up)
"The cohort is so small that it is not possible to do a statistically reliable analysis of trends. But as a rule, there were no ideological differences among those who had dropped someone from their Social Networking Site world because of politics."
I also think the rise of the Tea Party and continued harping by the Birthers for years have a lot to do with why they are blocked. You don't HAVE to listen to stupid.
