I think we need to stop blaming the thing that people are addicted to, instead of people who are addicted to it. People surely need to learn accepting the responsibility for their own actions, and stop always blaming other sources.
You are right with it, this is not the right time to blaming those people that are addicted to gambling and making gambling wrong. It is their choice.
But sometimes we need to think the things that is making wrong and too much really is not a good thing like in gambling.
If you don't want to blame the addiction of other people then they are the one that is going to accept the consequences of it. Not you and me.
