Subject: Re: Hamas "TERRORISTS!"
I don't know anyone who raises a stink about "have a blessed day". Perhaps 1% of atheists? The rest of us just ignore it. We may joke about it privately ("she said 'have a magically enchanted day'...snicker"). But we're not going to get into a theological debate with someone we only briefly encounter and will never see again.

Of course, maybe that's part of your definition of "militant atheist"? That's unclear. Some tiny subset of people may do that. Just as some tiny subset of women will give you a feminist lecture if you hold the door for them. That actually happened to me once in the hundreds (or thousands) of doors I've held for women. Generalizing that one woman to all women is fallacious.
