One of my personal favorite "excuses":
"I may believe in Creationism or I may believe in evolution. I choose to follow God."
(or some variation of the above)
It's a clear mixing of apples and bicycles:
* creationism is religious dogma.
* evolution is a scientific premise.
The first requires blind faith.
The second does not. Simple observation will suffice, if one has the patience and wit to observe the evidence. Accepting the scientific premise requires no faith at all.
...
However, I have found that the sort of folk who use this excuse, are the same sort of incurious folk that have NEVER had to discover something on their own: to them, it is ALL "faith".
Since they have never had an original thought or idea themselves, they have had to accept everything that they "know" from some authority figure: on faith.
So, I can sort of understand why they become confused.
Too bad we can't wipe out all those lying authority figures that are leading these poor, misguided sheep astray ... <heh>
