I may get some plaque as an award at the end of my life for doing a whole bunch of good things and at that time that is almost an acceptable tribute for not being an asshole. But that is all it means, I wasn't a full time asshole who hid behind some few good things in order to justify my own distorted sense of self worth. So no, I don't like it when a rotten person in or out of power does something good and then some start to hail them as decent folks. No, the decency is not earned by a rare occurrence of doing the ordinarily right thing. Decency is given when a lifetime of doing good things has been achieved or a pattern so entrenched in doing the right thing that not doing the right thing is unthinkable.
It is like our current dilemma. We have a republican president and a republican congress that fits the bill for doing mostly wrong and occasionally a right thing. So by my calculus they get nothing from me but disdain and a calling out from me until their time in public service is either cut short, or ends with their terms being up. Either way, they will never be legitimate nor will their defenders ever be legitimized. If my existence on this planet is to be what I know is right and good then I will not ever compromise down from that right and good but instead force those who cannot nor will not embrace the best of who we humans are to reevaluate their position up from harmful selfishness.
