Never nasty in return? he is one of the worst abusers of science and scientists I've ever come across, he waits a few weeks then trots out the same old ignorant balderdash about dino soft tissue/radioisotope dating/Darwinists/evolutionists/creationist scientists again and again. He never picks up a single idea from all the lovely people here who patiently waste their time indulging him. He is wilful ignorance with a smile on its face personified. I don't call that not nasty. I call it nasty.
