I'm looking to do a piece (of sorts) in which I bring up subjects that don't matter, yet everyone seems to have an opinion on. I can only think of one example at the moment, even though I know there are many more. I'm trying to jump start my brain on them and I'm looking for suggestions.
My first (and currently only) example, is Coke vs. Pepsi. I think the majority of people have an opinion (many of which are strong opinions) on which is better. Whether it actually matters or not. Any ideas?
Edit: Oh yeah, one of my ideas was Android vs. iOS but since it's linked to modern technology, I feel the more intellectual arguments have their place.
