I have little doubt that I share your principles. But there is a difference of opinion how to correctly apply them to the current situation.
Is voting for an immoral / amoral man an immoral act? If it is, how can one vote at all? Does this resonate...? "There is none righteous..." and "All have sinned..."? Therefore, if I am to vote, I accept that I will be voting for a sinner; a sinner like me.
So the moral choice is whether to vote or not. The matter of who to vote for is a matter of prudential / practical judgment. Since I lack omniscience, I am left to my God given reason to evaluate the more or less likely results of my choice.
If I decide that there is absolutely no difference, that the Republic is lost, and the end is nigh, I may need to consider if I am being tempted to despair. (That has always been an easy one for me to fall into.)
I have decided that rejecting the binary choice endorses, in effect, thw worse outcome of the binary choice (Hillary Clinton). And I cannot get myself off that hook.
There is, imho, no pretty option this time.
For me the fallacy of the binary choice is that it not only results in worse outcomes, but will continue to result in worse outcomes, and that will not change as long as we are slaves to that binary choice. One side will play the other against the other in the Kabuke Theater that politics has become, and when the red lights go off on the cameras they all go off to dinner together and raise a few to the dumbasses who keep them in their lifestyle. If the media people mind their Ps and Qs and prove trustworthy, they get to become somebodies and walk the halls of power, otherwise, they can do sports in Podunk.
I don't think the Republic is lost quite yet, otherwise, I'd be looking to do what my ancestors did when they received the land grant from Charles I. The writing is on the wall, leave while the leaving is good.
Instead, after decades of pushing that GOP button, I have decided that doesn't work. The Democrat button has had an 'out of order' sign on it from day one, but there are other choices.
Looking down the list, at the various Third Party options which have the potential to become major forces, I see the Libertarians, pushed by the media because they will likely not become the next Major Party because their platform will only be seen as liberalism with fewer rules. By giving attention to them, the Media can continue to marginalize the third parties and yet fulfill their obligation to report. Ditto the Green Party, but both have earned their place at the political table through the work of those promoting them. We are all sinners, but there are more flavors than chocolate and vanilla.
I like the platform of the Constitution Party, so I'll stump for it here. I see that as a return to the values which helped found this country, and I can back it without qualm.
If no one builds these other options by not paying fealty to the binary choices, we will be stuck with those same choices. Few on this site like the overall direction that has taken this country in the past half-century (Reagan was an outlier, a flyer on the political target of those 50 years) yet many are in thrall to the same system which brought them the left shift in the political arena, and promises more of the same in practice, if not with words. Those parties did not spring up overnight fully developed and powerful. It took work, and that means people who find the Party worth investing time and energy in will have to start and then continue to develop the support base needed to get to prominence as a political power. But it has to start somewhere.
If not now, when?
Otherwise, next election there will be another boogeyman facing another worse boogeyman and we'll have to vote for one or the other or the world will end. Again. Lather, rinse, repeat.
It is time to break the cycle.
