I recently had a discussion with someone who insisted this: when and where abortion is legal, it cannot be "murder" because murder only has a legal definition, 'illegal killing.'
I responded that "murder" also has a moral definition, at least "wrongful killing" or the "wrongful killing of a person."
This person denied this definition, insisting that anyone who understood "murder" this way is just mistaken.
How can this dispute be resolved? In general, how can disputes about definitions be resolved? A brief response is below. (Click on the post title to get there).
