Today we speak with actor and human-rights activist George Takei, not about his role as Liutenant Sulu on the original Star Trek, but about a far more troubling chapter in his life. In his new graphic memoir They Called Us Enemy, George writes in detail about his childhood spent in an internment camp for Japanese-American citizens.

It's a vivid account of one of the darkest times in America’s history as well as a wake-up call to a country currently detaining tens of thousands of immigrants and their families.  Is there still time to learn from our past mistakes or have the politics of fear and division already caused us, as a nation, to repeat them?
