Whoever choses to gamble has already subjected himself to a system that is 100 percent sponsored by the highest degree of uncertainty and should not be termed responsible. The measures to put in check when gambling to avoind being wrecked and addicted doesn't account for the title of responsible gambler.
A responsible gambler is someone who reduce their risks of getting wrecked in gambling, yes they choose to be a gambler, on something that's highly on probability, that doesn't mean you should not use your head.
Haven't you heard about gamblers that end up putting their families at risk? Some even sold their house which lead to their families living in the streets, a responsible gamblers are not selfish, they think about their families and also about themselves, home responsibility should always comes first, and if spare money comes you can use it on gambling, as a gambler if I am making $100 in a week I will risk only $5 on gambling per week.
I know what awaits every gamblers while they gamble, it's not always the pleasant result, if not, every gamblers will have good stories to share, but the opposite always happens, that's why taking big risks in gambling is not worth it.
