In tonight's Talking Points Memo, Bill O'Reilly took on an issue that he says is quickly becoming commonplace in the U.S.: Americans attacking other Americans over political issues.

O'Reilly highlighted the events of a June 30 gay pride rally in Seattle, Wash. at which two Christian activists were attacked after showing up to the rally holding signs reading "repent or else" and "Jesus saves."

Police arrested two men in connection to the attack.
