I am an upright and stubborn person, and I can't see the dark side at all. What should I do?

what can I do? You have no ability to change. What you have to do is to change little by little with your own practical actions and infect others. As long as others are not illegal, you have no right to interfere! It is possible that others will accuse you of meddling, or it may cause a lawsuit. Try to start from yourself and change others with practical actions. To put it mildly, don't interfere as long as there is nothing too out of line.
