What do you think about nihilism?

I think morals are practical and useful. I honestly can't imagine a society without ANY kind of morals. People need to have rules to govern their baser impulses. Otherwise we have no society. It seems to me like a lot of people want to live in a dream world where "enlightened" people can literally do whatever they want however and whenever they want, just because there are some rules in their current culture that they don't like. As long as the world has more than two people, there's going to be arguments, and as long as there are arguments, there needs to be some way to resolve them. And people? They don't resolve their conflicts simply or easily, there's too much stress and anger in the world for that.
