IMO, only superficial intelligence has flaws. A truly intelligent person wouldn't want to waste his or her time online arguing about matters that are highly speculative. Because no one is going to put those speculative matters to test and prove it as true or false as it's not science. The matter of sport is not a philosophical debate either.
A truly intelligent person is creative first and foremost; therefore, I see him or her spending their time doing something creative or thinking about it or just being - definitely not arguing online about highly speculative matters that can never be proven. It's fun yes, but it's also quite foolish and a complete waste of time. Even if they do get involved just for the sake of it, I still see them quitting while they are ahead quickly realizing that they are wasting their precious time arguing with people who will never change their mind no matter what.
