Showing that you're down with a cause is an easy thing to do if you don't mind getting tattoos based on the cause. It's an empowering thing to get a tattoo that represents your values as a person.
One person took notice of this particular dude's tattoos.
Across this man's arm is powerful imagery from the Civil Rights movement. He has a Martin Luther King Jr. portrait, a Malcolm X portrait, Joe Lewis, and several other pieces of black history tattooed on his arm.
On a trip to the dentist, he had his tattoos noticed by the person working on him, who decided to document the tattoos on Instagram.
