That's a shame, I've provided plenty of contrary evidence for this fairly unscientific belief of yours, now I realise that when you strategically stop replying when I get to the heart of the issue that's just you unable to face your own prejudices and actively switching off. Good to know though, because it means I can stop trying to challenge you on the topic. Shame that I had to waste so much time beforehand, though. Ah, well. Ignorance is bliss, etc.
