It's stupid to think the Tea Party is behind killing people. If anything the Tea Party is mostly old people who have high values and are very respectful of others. You can tell when a Tea Party was at a park when it's oddly clean, quite the opposite of when an occupy group vacates. Tea Party is very pro-military and Sikhs are highly trusted and respected by American and British military.
Venomous extremist racist or class hate is easier to find in Obama supporters and on MSNBC.
