It’s like saying that people are liars. You cannot make such a generalization just because some mishaps do happen. Sure somewhere someone will screw up, and this screw up can be spread quickly if someone forgets to check the validity of the claim as I did. No one is perfect.
The problem, and the frustration, is that this is a pattern on the creationist side. Misattribution of quotes, quote mining, outright quote fabrication...these happen quite frequently and regularly in this debate, and it almost always seems to tbe the creationist side doing it.
What's worse, though, is that when it is pointed out that something is a misquote, or misattributed, or even just wrong, many of the people of authority in the creationist movement will continue to use it. Those of you down in the trenches, as it were, may correct these errors, but for every one of you that do, many more are swayed by those at the top who continue to spout these, now, lies.
