I absolutely and completely agree with you, your view on this topic falls inline with mine as well, which I put down in comments hiding in some of the previous pages.
A child who will grow up into an adult to gamble will gamble, if he or she doesn't learn it from his or her parents, there are school mates to learn from, there are friends to learn from, there are work colleagues to learn from.
Using myself as an example, my parent never gambled, in fact, they are so uneducated that they don't even know what the word "gambling" mean, not to talk of engaging in it, but then, here am i, I gamble, and who thought me? Definitely not my parents.
Many parents who don't gamble don't even understand what gambling is, but that doesn't mean that children who have parents like that won't be involved in gambling someday. Because they will find out about it through their friends who like to gamble and this is the most common reason that in the end they learn and feel pleasure even though they always lose and in the end continue to gamble.
And for me, parents who like to gamble should not engage in gambling activities when they are with their children, and even if in the end they still gamble at least not because their parents or always see their parents gambling.
And your story is the same as mine, my parents didn't gamble and my gambling started with a friend who liked to gamble. However, I also kept my gambling activities a secret to them.
So, whether we play gambling game in front of our kids doesn't really matter, most slot games looks exactly like the many mobile games children play for fun, in fact, children can't tell the different except if told, so, it's very likely a child can watch his or her dad playing slot game, and assume that the dad is playing one of those mobile games the child's often plays.
And this is up to them, but it is better not to play in front of children. And many parents don't gamble, but they tell or give advice that gambling or slot games are not good, because slot gambling is the most popular. This makes people who are unfamiliar with slot games know about slot games but in a negative way. And this makes parents worry, even makes them the object of ridicule because of its popularity and also makes many people addicted and makes them miserable.
