wow! So because you hate gambling everyone else should quite gambling? That's quite hilarious.  If what you're are suggesting is possible in reality, then no one would be doing anything at all because what you love doing might be what I hate and if I should obey you and stop gambling, you should also obey me and stop what you love doing.

It's okay not to love doing a particular thing and every gambling site understand that they are not going to serve everyone one and so they are only interested in a selected population of people that are interested in their business. Gambling is some peoples business and you telling others to stop it is same as wanting peoples business to be closed down. What you would have said that would have been reasonable would have been that you hate gambling addiction and that people addicted to gambling should stop it. Then it would have been a reasonable conversation to engage in .
