But a much easier argument against sports betting is that it ruins the sports. Players throw. They get good at subtly cheating. The gambling apparatus latches itself to the sport, to the teams and players, the umpires and judges, the sporting organizations. With this much money on the line, it's not a matter of if but when games are thrown, cheated -- the bigger the game, the bigger the incentive. It's even easier now because of the amount of side/parlay betting that is available. It exhausts the spirit of competition.
Sports gambling is diametrically opposed to sport itself.
I think we need something like that for all sports here in the US. If you get caught fixing games or coordinating to fix bets in any way, you should be liable, fined, and banned from sports and anything sports related for life. If the entire team was in on it, the entire team gets banned for life. No second chances, no exceptions.
Or we could just make sports betting illegal again.
