Well I don't. And this belief isn't any more valid or invalid than mine, or anyone else's. Regardless of the flimsy definition of virtuousness, there are people out there who are hellbent on causing harm, and some are petty killers who are caught easily for tormenting and murdering their own little children, while others are in positions of serious power and leverage over nations who start wars and worse. Are there good people? Yes. Is everyone after peace, joy, safety and comfort? No Master Wayne, some people just want to watch the world burn.
The people in charge of Social Media aren't good people.
