How to confront evil?

Here is the question. How do you confront evil? Even in its embrionic stage like this young NAZI simpathyser white supremacists. Should you rise up (or stoop down) to their level and meet them with the same intensity at every stage like Shia Labeouf in the video below? A friend of mine once said the those people (referring to Sandinistas under Ortega in Nicaragua. The other side of the same coin) only understand one thing, violence. And I understood exactly what he meant.

I have no doubt that this young proto-fascist, with his skinny frame and nerd glasses, given the chance, would not hesitate to put a bullet in some minority's brain. Or drive thousands to their deaths, just like milketoast World War II NAZI Adolf Eichmann with his slim frame and horn-rimmed glasses, helped organized the the murder of millions of jews.

I read somewhere that it was easy for the ultra-violent to take over in democratic societies, since those that are cultured, liberal and civilized would try to talk reason and take the democratic road to power and government. By the time they figured out that those guys are playing by different set of rules, it would be too late and they would end up in exile, dead or in a concentration camp.

On the other hand Winston Churchill once said "We have not journeyed across the centuries, across the oceans, across the mountains, across the prairies, because we are made of sugar candy."
