Many have done so. I went to a religious college where we hosted Christian missionaries. They had many stories of converting Muslims using the same tactics as Daryl.
Jesus was a master philosopher and he understood how to convert. His time in the limelight lasted all of three years, but his religion is the largest in the world a whole 2000 years later. That's no accident. Love, compassion, understand, dialogue is still relevant and effective.
Muslims at jihad are a different matter, but as of this moment dialogue and empathy is the way to go.
