So, if you had the choice of floating around the sea on a little lifeboat waiting to be rescued, ok it won't sink, but you could die from starvation, exposure, or be tossed out by a storm, or a dozen other unpleasant things, and a large ship came to rescue you, would you refuse rescue on the basis that large ships are known, albeit very rarely, to sink, catch fire, get lost, be attacked by pirates, or refused harbour? That's how the stupid bloody argument looks from where I'm sitting. I'm pretty certain any sane person would get on the ship.
