Exactly. Side-ism — or the uncritical oversimplification of the complexity that is American politics and American demographics - is about as useful as racism. Honestly, what’s it good for?

No there absolute is: it's the side which hasn't ongoingly and repeatedly attempted to murder members of the other.

Property is not lives, and your "but the middle!" is meaningless: the middle if it exists is a group of people going "well, someone's dead, but also what about that vacant Wendy's?"

There may be no group with better humans, but ideologies can be better or worse.

"Ideologies" are just as bad as "sides".

Nobody really thinks that way. Better to discuss individual policies which will show that the vast majority of people comprise a complex mix of perspectives.
