While gambling can bring excitement and joy to some, it's essential to acknowledge its potential negative impacts and risks, such as addiction and financial loss.
We need to be as unbiased as possible when looking at any subject, and while I have no problems at all with someone gambling, as it is something I also do once in a while, we need to also avoid being over optimistic about gambling in general.
If this is not the case and the possible negative consequences that gambling could bring are disregarded, then it is way more likely that we could eventually suffer some of those consequences, something that is really undesirable as the losses which can be accrued are not small at all.
