Radicalism and extremism, while they are dangers, they exist in every society on some level.

Sometimes that irrational commitment to principle is what society needs to survive. Whenever you talk about radicalism, whenever you talk about activism, whenever you talk about progressive activity, that sort of moves the measure of liberty in human society forward, makes us all enjoy a better standard of liberty, it typically starts out criminal. It typically starts out a little bit shaky, and rather radical. And that's irrational to put yourself up to do that.

Being confronted with the realization that work you intended to benefit people is being used against them has a radicalizing effect.

We need to put the security back in the National Security Agency. We can't have the national surveillance agency.
