Every political side has quite a few absolutely tardbiscuit beliefs that they just cannot give up.

The left:

1) Binary sex isn’t real.
2) No evolution occurred above the neck.
3) Humans are a blank slate (and all related to that).

The right:

1) Climate change isn’t real.
2) Vaccines don’t work.
3) Markets automatically solve everything.

No side has any monopoly on truth or thinking coherently. Which is why I have no side.
