Critical rationality, role of opinions, scientism and postpostmodern silence

Once, one said: I have an opinion. It is more or less reflected, more or less differentiated or clear-cut. More or less based in experience or conceptual reasoning, etc.

Now it often seems: I would have an opinion. But I'm not an expert in this or that field. I'm not a scientist, not a politician (who has to be so considerate of all things), not an etc. I'm not completely absorbed in or part of the situation, so I cannot have a view about it (except for when it's societally or publicly deemed virtuous to display judgment and repeat ''opinion'').
