"There has been a rivalry" and "there shouldn't have to be a rivalry" are two separate things, and both are true. Just because it's a stupid argument doesn't mean the Trek/Wars divide, the Cola Wars of the 90s, or Nintendo vs Sega didn't happen. I was there, I saw them all. (Fought on the side of Trek, Coke, and Nintendo, for the record, but like when old western TV shows like the Rifleman have former Civil War soldiers, I look back on what happened as a tragedy all around rather than claiming a true victor.)
