Sometimes I think it’s ok; With a big officiating mistake, I would confront them face to face to protest the call if I could.
But I wouldn’t tell Bronco I don’t like him to his face. I wouldn’t say I’m glad he left BYU to his face. Why? It’s rude. I’d just ignore him if I felt that way. But if we’re in a crowd then it’s ok to adopt a mob mentality and do things we wouldn’t do face to face? I disagree. It’s classless, rude, bad sportsmanship.
