If you care about what people say as pertaining what you do you'll end up with their own decisions but in the aspects of gambling I would say when people's opinions should matter to you will be when your gambling habits is getting out of hand and then someone had to come in to say hey this way you're going isn't good and profitable so back off, when this is the subject of the day should be when you follow suits, I know of a truth some don't like anyone saying or contributing to anything that pertains them gambling but for me I don't care what people say cause I act responsibly with my gambling habits.
I very rarely notice that someone says something about me, or I simply do not pay attention to it. What I do, what I wear, where I work and everything else is only my business, my well-being will not change from someone's opinion, I will not live better just because I will try to please others, and if they do not like something about me, then it is not my problem. I perceive someone's opinion about gambling in the same way, I know that there are many people who consider gambling to be something bad, I will not argue with this, everyone sees what he believes.
