I suspect that arming TSA agents wouldbe cost prohibitive. They would probably have to do a thorough house cleaning to get rid of the employees who are unqualified/not legal to carry. Replacing them would be costly.
I agree with John. Studying the belief systems of others can give you a huge leg up on wirnessing to them. I like what James White says about it. You gain an enormous amount of credibility if you have taken the time to study their beliefs and can accurately represent them. If all you've got is having seen a movie or a read some article on the internet, they are much more likely to ignore you. You are also less likely to get snared by a lie.
There is nothing wrong with researching the origins of halloween to determine whether or not it is evil. I applaud the effort, as we should all know not only what we believe, but WHY we believe it. If I told you that Christmas was evil, would you stop celebrating it?
If that is true (I don't really know where the majority of fossils are found), it would be an interesting topic of research. Perhaps it has something to do with fault lines. I will have to find someone to ask next time I am at the Creation Museum.
