Uh, no? Of course I know Pratchett and he is wonderful, as are many other atheists. There's a certain subset of folks who think their "so edgy" atheism gives them license to be sexists and bigots and all-around assholes, and that is a trend which is worth countering. My impression is that it's a trend that Pratchett himself would wish to counter, in fact! It's a total strawman to say that the folks who criticize these people do so because of religion, many of them are humanists themselves and do so out of deeply humanist impulses.
What point did you think I was making when I wrote that? I didn't know who on earth the 'Amazing Atheist'
was until he kept being mentioned on here as either a straw man or straw poll. People plucking him out of their ass as opposed to countless thousands of other people who actually matter, time after time again in here is boring as f-ck.
