You decide to gamble with the amount of money you can afford to lose but I never want to lose my money by gambling. I have earned even one percent of my total money so I definitely don't want to lose even one percent of my money by gambling.
So does your statement implies that you are anti gambling? If so, then there's no reason for you even participate in the gambling discussion as your statement is more like discouraging people because of the possibility of losing. No offense, but gambling is not about losing that you'll have to spend for it, it's about enjoying, getting the entertain and you are willing to risk money for that, even if you lose.
His opinion is owned by him, but he sounds like a careful person, who doesn't want to lose a dime in gambling. Why he's here in the first place, may he be preparing or reading to know more about gambling? A person may not be interested in paying to watch a football match, but he can stay around those who discuss football. And he's completely welcome to participate in this discussion. Even if his points or response ain't valid, we also need his abstract comment to understand that not everyone thinks like everyone else in the discussion. Which balances the discussion and turns it into an argument. However, paying 1% of our income is not too much to ask, as we spend lots of money to maintain other responsibilities in life. Hence, anybody who feels like getting relief through gambling after a stressful day, week, or month. Can easily gamble for pleasure and revive themselves for a better performance the next week.
However, not all humans understand the importance of gambling, they think it's a waste of money. But, fail to remember that they also spend money on hotels, drinks, etc. Even those other ones don't have any possibility of rewarding the buyer with money. I understand he wants to stay safe and doesn't want to get involved in gambling because of all he's heard about gambling. It's good, instead of becoming one, which might get addicted to the habit. Everyone is entitled to what they choose to do with their time and money. Hence, no need to think he's anti-gambling, if he is, he wouldn't be here. And a person who gets discouraged due to his response also isn't on the wrong side. Gambling is a free-will activity, as the risk is enormous. Although the goal is not preventing people from gambling. If someone is unsure about their ability to manage gambling-related problems like addiction and financial loss, they can choose not to participate.
