Trust is a lot like respect in that a higher level of trust is earned, and so is distrust. I afford everyone a certain level of trust and respect until they demonstrate it is my better interests to do otherwise.
That's how I try to treat people. But I'll admit, I can overdo the disrespect/distrust at times, particularly over politics. I try to remind myself that.
But then I can't help but remind myself about potential for suspension of Habeas Corpus, screwing over veterans, old people, et al. for tax cuts, and dissolving our traditions and our place as a world leader in democracy, science, and global health, and I think, nah, eff-em.
Makes sense a turd wouldn't notice swimming amongst turds.
