Probably the main sameness comes from the ubiquitous human trait of narrowmindedness and prejudice (I always think of "prejudice" as "prejudgment").

Prejudgment leads to "broadbrushery", which is a far easier mindset to manage than juggling an infinite array of distinctions and contradictions, thus making life easier.

It's no secret that a life of ease is the Holy Grail of existence.

That might be a big reason that there is no difference.


You never change things by fighting the existing reality.
To change something, build a new model that makes the old model obsolete.
