Yep. Because if people can only post on what you know and are interested in it's going to be a bit restrictive. What would you have me do in this case?
See! I wasn't commenting on what you know - I was commenting upon what I DON'T KNOW!
I have the greatest respect for your knowledge which, obviously, is extensive - it is you way of commenting on the ignorance of others with which I take issue.
But let it pass, this is quite clearly a matter upon which thee and me are never going to agree, so let's just try and put up with each other and our little foibles eh?
