For most people, another person doesn’t need to be contrarian to be interesting.
I’d go one further and say that contrarians are intrinsically uninteresting. They are very predictable and tedious in their inability to accept ideas just because they are accepted by others. Being systematically opposed to ideas because they are perceived as mainstream is just as much of a fallacious reasoning than the other way around.
Except that there are many types of unpopularity that you have conflated.
Having intolerant views about trans people for example does not in my opinion make you interesting.
It just makes you intolerant.
Unfortunately, those are nowhere near universally unpopular views at this point in our human journey.
Sure, if both parties already agree on the meaning of "intolerance", but what qualifies as intolerance is exactly the dispute.
Corporations normalize utilitarian agency. Government social policing. University thinking.
Institutions never produced interesting science or engineering; people did. Institutions took all the credit.
