In the middle of all of the righteously angry outrage here, I respect that you are willing to express vulnerability. That's some powerful shit. Don't lose your humanity and don't lose your ability to be disgusted by evil.

And then, in your place, in your own way, identify it, expose it, and destroy it. In most cases, this will not require the force of arms or violence of any kind. You can fight much evil by quietly being an excellent person and an example to others. Start with your family.
