About 2.5 million Americans have a serious gambling problem (meaning that it has impacted their family), 5 million are compulsive gamblers and nearly 20 million have other varying degrees of problems controlling their gambling.You are taking very small issues and blowing them all out of proportion. There is nothing wrong with wagering on a football game and many people enjoy it every weekend.
I wouldn't ban it, but this isn't some minor problem. And the more it is normalized in our society, the greater the problem becomes.
By all means, enjoy the game. Place bets as you please. I certainly won't judge. But know that others are not as fortunate as yourself.
