I have studied some of the history around WWII and am at least loosely familiar with how Hitler and the Nazi party came to power. They used the SA, brownshirters, to create hate and anger at minority groups such as the Jewish people, gays, and communist. They were also used as a means of intimidation against those in politics that stood against the Nazi party. I haven't found any organization that Obama helps support that does these things. I figure people can claim Acorn was doing this but it seemed they were more interested in getting people to vote instead of getting people to stay away from the polls. The only groups I have seen doing this are those that appear to be supported by Republicans. The Tea Party appears to be more like the SA then any other mainstream organization at this time. I know they didn't start that way but people who want more hate out in this world got a few spokesmen to draw those types in. This isn't really any different then what the Nazi party did with Goebbels propaganda. If you go to http://www.huffingtonpost.com/cord-jefferson/becks-fearmongering-mimic_b_512150.html
you will find how closely the words of one of those pushing The Tea Party are to those that were responsible for a massacre.
I will continue this as I get more information.
