One of the simplest, most effective, ways to fight evil is by telling the truth. Always. Evil very rarely comes to us naked. Its agents understand that honesty is their enemy, that they Must lie about their true intentions, they Must present a good face to its victims in order to take them unawares. All throughout history, evil men have lied their way to get what they wanted. Mohammad presented himself as "prophet" because he would have gotten nowhere if he presented himself as he was, a mass-murdering pedophile. Obama presented himself as "Hope", because "Destroying America From Within" would have gotten him nowhere. As Ayn Rand wrote, "evil is impotent". Without lies- maintained even after they get what they want -evil men would have a hell of a time getting away with murder, all while desperately trying to make themselves believe that they're actually good.
