This week we asked "Star Trek" actor George Takei about his new documentary "To be Takei," the move by the Supreme Court that will bring legal same-sex marriage to more states, his time in an internment camp during World War II and the key to his success on Facebook.

Q: I just wanted to get your reaction to the move by the Supreme Court this week which expands the number of states where gay marriage will be legal.

GT: Well, it's more than half the United States now. Even when we had 19 states, which was a patchwork, we had in terms of the population, more than half the United States because all of the metropolitan areas were in those 19 states. And now with more than half the states, half the United States with equality, it will be not very long before we'll be able to pledge allegiance to the United States of America, where all the states will have equality for all Americans.

Q: Getting to your documentary, one thing that people might not realize about you that I learned yesterday watching the documentary is that you were actually one of the Japanese-Americans, along with your family, put in an internment camp during WWII. And so my question is, how do you get over something like that, and do you ever really get over something like that?

GT: No, you don't get over it, and you certainly don't forget it. But you know, I was a child then. But I had an extraordinary father who really experienced the anguish, the pain, the outrage, the loss and the humiliation of that unconstitutional act most profoundly. And yet, he was able to, when I was a teenager, and I engaged him in discussion after dinner, he was able to explain to me the core ideals of our democracy. He said "our democracy is a people's democracy, and it can be as great as the people can be, but it's also as fallible as people are."

Q: What do you think the key is for celebrities to getting involved in the causes they care about without making it about themselves, if you know what I mean?

GT: Yes, I do. But you know, about themselves is not bad either because then they personalize the issues, and when an issue has a face on it, then the listener can see it much, much more specifically and humanistically. But, yeah, you're right, it isn't about themselves, it's about whatever issue that they're talking about. And I think in order to be successful in your political discussion, you've got to keep your mind and focus on the issue itself, not on self-aggrandizement. And I think some people do that very well. I mean, I think someone like George Clooney, who discusses political issues with both intelligence and information as well as wit. And he's very effective at it. Going back in time, Jane Fonda discussed issue[s] but I think there was too much of a celebrity glow around her. And it became about her, and you know she was criticized for that. But I think the serious ones focus on the issue itself.

Q: You talk about in your documentary of the representation of Asian-Americans on screen. What do you think of the presence of Asian-Americans at this point in time in our media?

GT: We've made enormous strides. You know, when I started out, I could say safely that almost 100 percent of the visibility that Asians or Asian Americans got on American media was in stereotyped and very unattractive stereotype roles. But today almost any television series that takes place in an urban setting, whether it's a hospital show or a detective show, there's that diversity of America reflected. And certainly Asians are a part of that diversity. Now we have leads in TV series as well. In this new series starting up, "Selfie," the actor that plays the young Sulu in the rebooted "Star Trek" series, John Cho, is the lead in that. And so, we've made enormous strides. But I still admire the African American community because they have made a giant leap. They now have bankable stars, and when you have bankable stars, then the stories of those films or TV series are told from that minority vantage point.

Q: You have almost 8 million likes on Facebook. What do you think the key is to your success on that platform?

GT: Well, through trial and error I discovered that the key to getting a lot of likes and shares is humor, and particularly, Grumpy Cat. That's almost universal. But then the other thing is timing and…having a sense for the climate of the times. Certainly after a major tragedy, after a Sandy Hurricane or events like that, you have to temper the humor and deal with the issue there. But generally to grow your base, it's humor. And then to get those that are really issues-oriented people, then the social justice issues that I inject is what gets the quality of the base notched up.

Q: Do you have a candidate for 2016? Of course, a lot of people talking about a Hillary Clinton run. Do you have a candidate that you'd like to see run?

GT: Well, we were great supporters of Bill Clinton-enthusiastic supporters. And we worked with Hillary then as well. She hasn't declared. There are some interesting Democrats that are making sounds of throwing the hat in the ring. So I want to be fair to everybody. But we are rather predisposed to being Hillary supporters. But I'm keeping my mind and options open.
