I don't have the time or energy to respond to all of the casuals but yes, if you cannot sit back and root for your team and the players on your team, you're a casual to me. You're caught up in things like jerseys, star power, stats, etc. Plain and simple, if you don't want to be happy after your team wins and you wanna nitpick every player, coach, decision over something you have absolutely no control over, do you boo.
Contrarily, I am such a huge fan that I have been cushioning the blows of my teams losses for years. If I bet the other side, it's a win win. I literally just paid for my tickets behind home plate in the world series watching my dodgers win again because I previously bet on the Blue Jays to beat them. The Jays won, I won a chunk of money and cushioned the blow, took the winnings and got incredible seats. I don't expect everyone to be able to understand this or afford this life style, but it's just what I do. I already admitted to losing thousands on betting against the panthers, I already ate my crow, I'm a man and can admit when I am wrong, I can laugh at my self and not take things like sports so seriously. I will most likely keep adding the panthers opponents to some of my lottery parlays too. Sue me!
