mother fucker, I've just lost this twice here trying to get it all down without timing out.
Anyway, here we go again, cos this shit is important. It started out as a post to congratulate you on your timely contributions, but I felt the need to press on. While the initial iteration was eloquent beyond belief, it has suffered some in the multiple retyping, and as such you'll have to make do with the following points for consideration.
* I have NFI what your chart is showing - religious breakdown of mcdonalds payroll, the world, multiple sex offenders? All seem plausible. This is probably quite a different set of data to what you'd find in Lexicographer's university, which is what he was speaking about. Seeing as he beat you to the punch on setting the topic there, if you'd like to disprove his statement about an atheist majority at his university, you'd probably need to discuss it based on that, rather than the good old "hey anyway, look what I found, some random shit!" approach. I think you either deliberately chose to miss this, or misunderstood the post and then went on to argue with an assertion which was not actually made.
* I'd like to think that you'll find more atheists in a university than you would in the wider community, as universities are apparently about knowledge, which is the opposite to religion. This is important to turn over in your head, as it's a very subtle reason as to why some random pie chart from the net probably doesn't correspond to the point which Lexicographer was making.
* Atheists are hard to count - subjective classification, potentially apathetic towards religion-themed research, pressures against declaring atheism in some cases.
* Is there any particular reason why, in the context of what he was saying, Lexicographer wouldn't have also been referring to the "no religion" group from your chart? While (in the case of your data, not his) this still wouldn't have represented an atheist majority, it also stops looking like the ridiculous overstatement you've chosen to interpret it as.
* In future, please jump on posts by people who are likely to reply - it'll save me the time and effort of doing it on their behalf (I try hard to resist the urge, but sometimes I can't help it).
* Provide references when supporting your discussion with someone else's data. It allows people to be much more specific when explaining to you why you are wrong.
