How come some of them went to their deaths for standing for something they knew was a lie?
What is really going on with the people who so regularly wheel out this vapid tosh? I mean, given how often it's employed as some sort of killer point, I find it impossible to believe that any reasonably intelligent, normally-constituted adult human being can be unaware of the counter to such a feeble point - people don't as far as I'm aware die for something they know to be a lie (that's to say a conscious and deliberate untruth), but we've abundant evidence of people dying for what they sincerely believe to be true but about which we consider them to be mistaken or otherwise misinformed. Sincerity of belief does not, has never and will never be any hallmark of correctness of belief.
This has been pointed out so many, many times, by me and by numerousothers, that I can only surmise what when somebody proffers this perfectly reasonable point, some sort of intellectual roller shutter door comes down in the brains of certain religionists such that they don't see it or are unable to process it, and can be found shortly thereafter using it all over again as though they'd never encountered any challenge to it whatever.
Perhaps somebody can comment on what's going on, because I for one am heartily sick of seeing this zombie pseudo-point pop up time after time.
