Let me summarize:
We expect Leftists to stab us in our chests, it is our responsibility to defend ourselves from them, and if they stab us, it is the equivalent of the scorpion who stings the frog-it is the nature of the scorpion, and the frog errored in not remembering that the scorpion is an enemy.
However, when we get stabbed in the back by people who we fully and rightfully expect to protect our interests, that will make us far angrier. The fault is not ours, the fault is in the betrayer, who was expected to fight on our behalf, not sabotage us and stab us in the back.
