What to do?

So we all know that this time of year, aka the holidays, bring families together. It has been nice being home and getting to see my family. Over the last few days I have my parent's have had one of my aunts and her son over to visit. And it is nice to see them since I haven't seen them in at least 2 years. My aunt is for the most part conservative but then again so is most of my family but at the same time we are far from religious, although apparently my grandfather is very liberal which made for an interesting situation yesterday when we went to go visit him but that is another story all together. I love my aunt I think she is funny but tonight she said something that disappointed me.

We were watching the TV show The Big Bang Theory, Monday's at 9:30 on CBS, and the intro song mentions human evolution. My aunt said, "I don't believe in human evolution." There was the silence where no one knew what to say or do. One thing is for certain as much as my parent's might not completely understand science they have at least tried and they tend to accept most of the theories, sometimes a little too much against my advising but it has never hurt them. That maybe why both my sister and I have always been interested in science. Anyway this silence lasted for what seems like a couple of minutes but was probably only a few seconds until the next cheesy commercial came on. I will admit I didn't say anything and I probably should have but I tried to make my annoyance known.

So now my question is this: If you were put in the same situation what would you have done? Would you have sat their quietly like my whole family did or would you have said something challenged her or heck maybe you have some sort of middle ground. I just didn't know what to do at the time and just let it slide, since for most things we have very similar thought processes and I don't get to see her very often. I don't know how many people follow this blog but I figured I would ask that question to see if anyone who does read has any suggestions for next time.
