I would go ahead recommend and not be a pompous ass who says sportsball, you are not better than others or unique because you don’t like sports.

And then to answer your question I don’t think it has much to do with the sport itself.

1. i think it’s the trigger not the cause.
2. Big crowd+alcohol and other substances
3. the crowd anonymity effect or whatever if it even has a name, if only one person in a crowd starts kicking over a trashcan and gets some cheers, it can and will quickly spread through the crowd who will start doing it and/or escalate what they do as they feel kinda safe, because they are not doing it alone. The same way when you do something you are kinda afraid to do doing it with a friend (if you had any) gives you more courage.

Or to quote Man in Black “A person is smart. People are dumb, panicky dangerous animals, and you know it.”

Think about January 6, you think if you ask then individually if it’s a good idea to go to the capitol alone and overthrow try to overthrow a government and theyd probably call you stupid for the idea, but put them in a crowd where they mutually encourage each other and give each other a sense of security and they will go ahead and do it the dumb bastards.
