I always love it when people argue against religion for saddling people with unnecessary guilt.
Then, when you say that religion is a positive force in your life, they say, "Well, if you need that kind of reassurance, then maybe it's right for you."
Which is it, scourge or crutch?
Of course, to believers it's neither and it's both: it's an obligation.
But to those fools, anti-religion is their drug of choice, and they'll use any argument or combination of arguments, however self-contradictory.
