Fair points all round. Some of the diatribes I pen are hugely influenced by things I have read elesewhere, I just change them to suit the circumstances I am detailing. In fact, I think myself and Mr Beelzebub share some sort of telepathy as I wrote a rant at work and sent it to a few (select) users - not long after, the great Barry wrote words in a similar vein. Perhaps we all just get the same bile, over the same subject, at the same time.
But, I suppose, this is what happens when you actually take time to look at the news, analyse it and spell it out to people in words and with humour that keep their attention.
