(You might end up with your head cut off.
I am not currently aware of anybody that has gotten their head cut off because they disagree with the Theory of Evolution.)
I'd appreciate it for the sake of integrity not to pull my words out of context. The context of my "You might end up with your head cut off" comment is reagarding criticism of Islam (you may be aware of the Dutch incident. If not, please read up).
The fact is there are many questions that are asked about evolution have not been answered (there have been a couple of threads about those questions just today - I don't want to be unsportsmanlike and cut and paste pages of text and take your time to read them if you don't want to). Some evolution teachers, in order to sidestep the conspiracy, have said that they will not entertain questions about evolution as they are there to teach about science and they do not play a role in the spiritual education of the students. They very cleverly equate asking questions about evolution (requesting answers about FACTS) to spiritual issues.
I've read some of the threads today, and gotten involved in others. What happens a lot is that students will come in with something like "10 questions to ask your biology teacher", and then will disrupt the class with it. Most students that do this don't even understand the questions that they are asking.
If they really wanted answers to their questions, they could look them up on the internet. It is a waste of time for a teacher to have to deal with things that are outside the curriculum, just because some kid thinks he's smarter than everybody else, or because his religious beliefs make him feel superior.
Personally, if I was a teacher under those circumstances, I would ask the student to write down the questions, and use it to create a research assignment for everybody to have to do. I would also tell everybody who to thank for it.
