Here's another example that shows just how 'accepting' liberals are of people from all walks of life.
High School teacher Al Levie refused to accept an MLK award from Rep. Paul Ryan because, well, Paul Ryan is a conservative no matter how Levie tries to frame it. Levie stated that "Paul Ryan has no business being at an MLK event." That's a pretty bigoted action.
The event took place at the Gateway Technical College MLK Humanitarian Awards on January 16, 2012.
UPDATE: Levie's speech can be found here.
