Maybe, like myself, you're just aging into being a bit of a conservative.
Eh, I don’t think not wanting gambling and amoral behavior to consume society makes me a conservative in any real sense of the word. More just common sense pragmatism, is how I’d put it.
I think most serious left-wing people also hold a strong aversion to gambling on the grounds that it's financially exploitative and can be viewed as a regressive tax on the poor/uneducated.
Conservatives don't have a monopoly on morality.
Let's not label ourselves. Once we do it, we have this tendency to think in black and white terms. Like, I wish people didn't divorce, so kids could have stable families, does this make me a conservative? Maybe yes, or maybe no, because I don't want to FORCE people to stay married.
But once I label myself a conservative, I am stuck, and now have a new set of friends with the same label, because I am labeled myself, and they have all those radical ideas, and then I have to pretend to believe and ending up believing them too.
Of course, the same applies when you label yourself a progressive.
