"Can anyone out there score me some consecrated communion wafers? There's no way I can personally get them my local churches have stakes prepared for me, I'm sure but if any of you would be willing to do what it takes to get me some, or even one, and mail it to me, I'll show you sacrilege, gladly, and with much fanfare. I won't be tempted to hold it hostage (no, not even if I have a choice between returning the Eucharist and watching Bill Donohue kick the pope in the balls, which would apparently be a more humane act than desecrating a goddamned cracker), but will instead treat it with profound disrespect and heinous cracker abuse, all photographed and presented here on the web. I shall do so joyfully and with laughter in my heart. If you can smuggle some out from under the armed guards and grim nuns hovering over your local communion ceremony, just write to me and I'll send you my home address," - PZ Myers.
It is one thing to engage in free, if disrespectful, debate. It is another to repeatedly assault and ridicule and abuse something that is deeply sacred to a great many people. Calling the Holy Eucharist a "goddamned cracker" isn't about free speech; it's really about some baseline civility. Myers' rant is the rant of an anti-Catholic bigot. And atheists and agnostics can be bigots too.
