Their lack of self reflection is astounding.
The reason they demonize everyone else is because they have canonized themselves.
Everyone else is a demon by simple virtue that they are not Proglodytes and to Proglodytes all Proglodytes are saints.
But conflict is inevitable, in all social structures.
Conservative society endures because we assume we are all fallible and as such we endeavor to create a system where one party cannot control the others. Thus when we have disputes we don't feel threatened because the party we disagree with has no control over us.
But control is central to Proglodytes. They demonize and canonize in order to justify assuming control. But when there is disagreement they absolutely feel threatened because the other party has control. Everything is an existential threat to them and it is actualized by a paradigm that treats all enemies as demons.
The internal inconsistencies of Proglodytism were fated to become manifest as soon as they gained control. Obama did that in 2009 with a dem congress and senate (and limp-dick GOP leadership in 2012 and on) and here we are.
We will win because we design for winning on our own terms. They cannot win because they cannot maintain that which allows them any gains.
