Keith,maybe it's the way you do it.
Repeating your argument ad nau-se-am in much the same way,as you often do and demanding to be be told what is wrong with your statement comes across as a failure to grasp other peoples opinions.
In many threads other posters have tried to explain why they disagree with you,only to be met yet again with a repeat of exactly what you said before, this leads people to believe, as others have said "you simply don't get it"
You often also seem to subtly change what you said previously, thus giving the impression that you deny you said what can clearly be seen in a previous post.
You problem seems as I said is your way of argument it simply irritates
people and doesn't achieve anything other than annoy them.
Hope it helps you see why you get the response you often do.
