Is there any positive at all about gambling?

When I read the other sub "gambling" I see many people look differently at gambling, but are they living in denial? Is it like being addicted to smoking and boast about doing it even though it's harmful?

Feels like to like there are 2 nations, 2 different groups .... one is problemgambling and the other - what kind of people are they? Why if I post anything there with the nature of posts here I'd be criticized over there in that sub?
