I agree to an extent but there's a certain point where cognitive dissonance can't be the excuse. We're long past that. There have been countless wake-up calls, off-ramps, breaking points, etc. if absolutely none of them, not one, has made you stop and reconsider after all this time, then what will?
Frankly, if you're so ethically and mentally shattered as a human being that cognitive dissonance is enough to make you support a man that has done every possible thing under the sun over the course of 8 years to illustrate what a walking cancer he is on society, then there's no fundamental difference between you and the actual goose-stepping supporters, because you will ultimately behave exactly the same regardless. There's nothing anyone can say or do to help you, so why should anyone waste their time concerning themselves with whether or not you're a true asshole or just mislead.
