Calling what goes on inside Planned Parenthood “murder” could possibly incite the crazies among us to this sort of behavior. If your neighbor decides not to have another child, and visits a Planned Parenthood to have an abortion, that is different from your neighbor coming to your home and shooting your child. The second situation is murder and deadly force is clearly called for. In the first, perhaps a personal conversation with your neighbor would be appropriate. The crazies out there are not capable of such discernment.
Do you deny that what goes inside Planned Parenthood is murder?
