SlugForAButt in yet another purposefully taken out of context shocker.
Let's look at Harold Shipman, yes he was techinically a "doctor" if you want to be technical about it, but everything he did went against the practise of ethical medicine, which arguably would mean he wasn't a "doctor".
He went against the Hippocratic Oath which should mean he wasn't practising medicine correctly, and therefore isn't a doctor.
Say I get a new job as a carpenter, and through my time as a "carpenter" I demonstrate a complete lack of understand of what a carpenter is, and get fired for it, I can claim to be whatever I want in what ever way I want, still doesn't mean I actually am a carpenter. I could go around in overalls and a bag full of chisels, I'm still not a carpenter if I can't do carpentry.
Same principle works for religious folk. Those Catholic Priests weren't truly "religious", I wouldn't even call them Catholics by its correct definition, as surely they would be fearful of God's punishment from their acts?
Or the IRA who carried out countless terrorist attacks in the name of Christianity. They can claim to be Christian all they want, if their actions say otherwise, then it doesn't matter what they claim.
I can claim to be good at drawing, but it doesn't mean anything if when it comes to demonstrating my drawing abilities, it's apparent that I am actually really bad at drawing.
