Who gets to decide what is nonsense. What happens when society thinks YOU are the one with nonsensical beliefs?
"Galileo agreed not to teach the heresy anymore and spent the rest of his life under house arrest. It took more than 300 years for the Church to admit that Galileo was right and to clear his name of heresy."
When people are directly threatening people because they are even slightly linked to 5G towers, or they're peddling nonsense like 'drinking bleach will cure you of corona', then I think it's fair to draw a line in the sand and say those are dangerous, nonsensical beliefs.
But to be fair to the person you’re responding to, you still haven’t answered his actual question - who gets to decide?
The example you gave is only “obvious” because the majority think so. However we’re increasingly living in an environment where people are “fleeing the centre”. People have abandoned authority, and are increasingly abandoning science, even to the point of doubting or reinterpreting their own lived experience.
The key to “common sense” is “common”. When very little is held in common, where do you find common sense?
This is precisely why, in my view, the single greatest danger to mankind is - a “meta-danger” perhaps - is the explosion in deliberate attempts (irrespective of motive - lulz, commercial profit, political influence or psychological warfare) to misinform, sow discord, and erode trust. It is an absolute scourge and is already starting to bite us in the collective arse, by limiting our ability to act collectively for objective common good.
