I've always thought Myers was a sneering, condescending prick. Much like Dawkins, but at least Dawkins is staying true to his principles when it comes to science and religion.
Yeah despite writing a book called "The Happy Atheist", and claiming to be progressive and a feminist, PZ Myers appears to be fairly notorious for his angry, hateful, bad behaviour.
E.g.:

Personally I was always a fan of Sam Harris, in that, whether or not you agree with him, (I often don't), he conducts himself in the right way and is always capable of calm, rational discussion of a subject.
Dawkins may be far from perfect, but he is nothing like PZ Myers imo. Myers is just an unpleasant bully. (That's the polite way to put it.)
