Well I think it should be balanced, people can't talk about the bad side alone as this can discourage prospective gamblers from going into gambling. In as much as we like to tell people about the negatives things about gambling, we should also let them know the things they stand to benefit if they gamble responsibly. This is just like someone only talking about the bad things you have done, but will never mention the good things you have been doing.
It just seem like one needs to be properly guidedon the wings of gambling so therefore there's nothing wrong in letting them know the both sides of gambling and leave them with their own choice of decisions but they'll be glad they knew the negative snd positive sides. I believe it's based on the negative occurrence that has led people to withheld the good sides of gambling.
