Stupid is allowing this opinionated not academically oriented thread, while putting referenced not opinionated questions on hold.
Stupid is looking through the answers and seeing no references and strict subjective opinion while deleting other comments for the following same reason.
Stupid is looking through the members having a thread put on hold and seeing the same names pop up continually.
Stupidity is saying something is vague, therefore if I do not understand it is wrong.
Crazy is the continuation of it.
Truth is the stupidest and craziest thing of it all.
In other words stupid and crazy are simply grounded in the symmetry between perspective and group agreement. A person is stupid or crazy if they do not share the same perspectives and patterns behavior of the group. The same applies inversely for groups.
Stupid and crazy are points of view, thus assumed. One implies a finite action, the other a course of actions, but both as assumed through the nature language contexts are reversible.
They effectively mean the same thing, as both are strictly contexts for expressing behavior which diverges from a group.
Stupid and crazy are ways of saying "the context as a perspective does not align with another context as a perspective.
