Although I agreed with the information in the exhibit completely, I kept wondering if the information could have been more diplomatically in a nation that has such a large population of evangelical Christians who probably hold a literally biblical view of the beginning of things.

Is there a way for us to be more diplomatic and tolerant without compromising our own views?

The thing about information is that it is neutral. Information is tendentious only when it is presented partially (which, admittedly, happens a lot). Honest presentation of information need not be diplomatic. That implies dressing up so as not to offend. When it comes to good information, well out with it, I say. All of it. There is no reason why information, dispassionately presented, should offend anyone save those who are determined to be offended at all costs.
