Richard Dawkins. Too much or bang on?
Being a Biologist puts him out of my scope of interest. However, his stance on religion is quite extraordinary. He is passionate and measured in a delicate balance. You can look him up in YouTube, plenty of interesting footage on several topics. His credit is well deserved
He was all fired up. How could he have bashed his way through the world of religious stupidity if he was not 'too much'? Newer atheists have an easier time than he did, because he did it first. I think he should never have lowered himself to engage with Twitter but overall (having read two of his books as well as the usual), I think he has contributed a huge body of knowledge to the world of genetics and helped cut the feet out from under an arrogant and often criminal clergy.
