Feel free to challenge what I write here:

Note to anyone who might read anything I post here who disagrees with what I've said: Feel free to challenge me if you think I'm speaking nonsense. I can take it. I've been wrong before and it is certain to happen again. Probably quite often. Don't worry I wont be mad. I state my opinions with conviction because I'm generally confident I'm right, but I am never certain. And call me crazy but I usually love being proven wrong.
