Vancouver’s Joey Gibson always paid some attention to politics but had little practical interest in the process. Then he took to the streets outside the Republican National Convention in Cleveland last summer.There, the leader of the Patriot Prayer online community-slash-movement, whose organizing and activism has garnered national headlines after recent clashes on college campuses and the streets of Portland, was caught on camera tearing up a demonstrator’s anti-police cardboard sign. “Why would you destroy my property?” asked the man, who was wearing a T-shirt that read “F*** the police.”Because Gibson, 33, was fired up. But then he felt bad for ripping up the sign. He handed the guy a $20 bill, and the interaction ended with a handshake. Now, a year later, Gibson said he is still evolving as an activist and organizer. On Facebook videos and YouTube, he preaches “Hatred is a disease.” He counts the Rev. Martin Luther King Jr. among his political heroes. He once invited a transgender person to speak at one of his rallies because he said it’s time all people were accepted. Yet trouble seems to follow his activism. Most recently, fighting broke out as marchers with Gibson met with protesters Friday at Tom McCall Waterfront Park in Portland, during the Waterfront Blues Festival.
