I would love to know your opinion over this question above as it's painful to see that what you do or what gives you joy at times people often term it as something bad or possibly as an irresponsible people.
If it was you, what would you do knowing too well that people who gambles are often seen as useless people and irresponsible people due to what some fellas has presented themselves into while gambling without at least showing any sign of responsibleness. Also, What do you think can be done to see gamblers as a responsible people in our society?
Let them think negatively. Perhaps that only gives them stress thinking of others' lives while we enjoy our day gambling. There are many and very common in a place where the only thing they can do is monitor the lives of their neighbors.
I don't bother myself hearing them. Besides, I know myself that I am different from other gamblers. I gamble responsibly and have never been in trouble. There is nothing to explain to these people because they will not listen to us. Maybe someday they will just realize that they are wrong.
