It's a fair point though, BA. Why give thanks for the pretty and fluffy and not the bacteria and the viruses?
Agreed - the song, by the Monty Python team was intended to be taken however listener chose, but it was a genuine demostration of the fact that Christians are quick to praise the positives that they attribute to their deity but stay as far away as they possibly can from agreeing that he is responsible for all the nastiness and negatives, as he supposedly made everything, he is also responsible for.
BA is quick to accuse anyone who criticises this kind of behaviour on the part of his Christian fellows of being insulting but is quick to insult his detractors when it suits him. But then he will tell you that he doesn't deserve it because he is defending the truth! A truth that denies the existence of half the truth - see above.
