I mean, while I agree with where you are coming from. The part of weak/strong will is doing it in the first place. I was peer pressured to smoke at age 14 by all my (ex)friends and instead I just left. Smoking or Drinking or even gambling because of social circles is stupid. And if you get addicted because you didnt want to be called a square or whatever then its hard for me to care.
Now in the case of kids gambling specifically, obviously I think it should be enforced better. But im not gonna sit here and hate on a streamer for taking a sponsor, nor am I gonna waste my time feeling bad when there are 7billion people and people go through way worse. At the end of the day its either
A. the parents fault for letting their kids gamble
B. The persons fault for gambling (once their 18+)
Probably my harshest take as Im usually a humanitarian. Maybe im still in the wrong, but I just cant find it in me to care about these people.
