Somewhat, yeah. You're overwhelmingly a product of your parents opinions and you're largely doing what they tell you to do or allow you to do. Because of this, it just comes across as shallow. Greta complained about how she should be at school and was blaming the politicians. In reality it's her parents' fault she's not in school.
Sorry mate but that point about complaints is completely wrong.
A demonstration, whatever the type, is exactly that by definition. People interrupting their jobs because officials are not doing theirs well enough.
