Why don't Christians pluck their eyes out when they see something offensive?

Ohhh I so love your question!!!! It's simple really. They have no self control, which is what the Bible instructs Christians must develop. Far better for them to stand around & demand that offensive material be removed than to develop the ability to do what that verse instructs them to do in a literal sense. Whatever it is in a Christians life that is causing them to sin is to be avoided, thrown away, put aside, and it is to be done by that person's hands & mind. It's far much more fun to them to continue doing their dirty deeds behind closed doors & just expect everyone else in society to change their lives so they don't really have to.
