There are some very traditional nationalistic rivalries. Puerto Ricans vs. Mexicans...... U.S. vs. British. Nothing wrong with that. And anyone who doesn't realize these rivalries exist, is a little out of touch with boxing.

Having said that, I'll admit to being VERY nationalistic. But I also look at fighters' individual merits. Style, class, skill, exciting to watch, quality of opposition. Those are all factors I look at when choosing favorite fighters.
