For years now, I've been talking about the rise of the extreme right in the U.S. Since 9/11, white nationalists have killed more Americans on U.S. soil than any foreign or domestic terrorist group combined. It's something we don't categorize as terrorism or extremism. We often brush it off as mental illness - things like Oak Creek Wisconsin - and these people are certainly tied to white supremacy, have written manifestos. We've got a major problem in not calling that terrorism.

Looking back, I've learned that everyone is searching for three things: Identity, community, and a sense of individual purpose. These are fundamental, and if a person feels marginalized or disenfranchised, they're likely to turn to something negative, maybe drugs, maybe promiscuity, or maybe a white supremacist group.

There were a lot of people in our nationalist group who went on to become cops and firefighters and correctional officers. Unfortunately so. I haven't talked to them in 20 years, but just by keeping tabs on Facebook I know that there are some who've gone that way. And they've never indicated publicly that they've changed their opinions. It's a minority.

30 years ago in white supremacy, we had a strategy called leaderless resistance. The concept was: stop shaving our heads, stop getting tattoos and instead try to blend in as much as possible. It was a really concerted effort to try and tone down the rhetoric and make it a little more palatable to the mainstream. And it certainly has penetrated the mainstream now. We're seeing people who were supportive of our cause back then also supportive of Donald Trump's cause, certainly with the recent cabinet appointments.

I have two sons, ages 23 and 25, and know that parents need to listen more and speak less. Young people today don't always know what's going on or how they fit in, and if someone walks up to them and says, 'Hey, kid: If you listen to me I'll give you power and a sense of purpose,' it can hold tremendous appeal.

Actually, I don't think most people join white supremacist groups because of the ideology or dogma. They gravitate to these groups because they've hit potholes in their lives and there are things they can't figure out how to navigate on their own. This might be bullying, parental abuse or neglect, mental or physical illness, or, for adults, unemployment.

I read recently that in the U.S. today, the majority of people under the age of 21 are immigrants or first- or second-generation Americans. We need to integrate young people into community life far more fully than we currently do and give them role models they can relate to. We can do this if we make it a priority.
