ummmm, if I were to call aog a bigot (and I don't think I have) it would be on the basis of reading a great many of his posts before drawing conclusions about the poster. The accusation against andy was made on the basis of a single post, which is a pretty flimsy basis for any kind of character analysis - and a particularly misguided one in andy's case, since he's made thousands of clearly unbigoted posts. If she had any objection to this particular one, she should have objected to it - not to him.
The Ed is entitled to set standards of civlity on his own website. If they are tighter than they used to be - and I don't think that's actually the case - then that's his job and his rules. Those who disagree with them are free to leave, as naomi has apparently done.
