If you've ever participated in a political debate, you're familiar with this one.
Putting two strong-minded people together will always be difficult. What's even worse is two differing age groups with very unique perspectives on life. When a two-sided topic comes into discussion, it usually starts off civil, becomes emotional, and then quickly turns to not speaking at all. This results in both people portraying a closed-minded personality. I hate seeing this between two generations, it looks like hatred if you're observing from afar. Can't someone just be the bigger person?
