Sam, just so you know, many of your sentences could exchange Trump for Hillary and be exactly what Trump supporters I know say. Especially this one:
> [Hillary] shows little respect for the Constitution, the Republic, or for human decency, and I fear for national security if [she] becomes our president.
Other sentences would just exchange antonyms and not make it sound any better. You call Trump isolationist, they call Hillary interventionist.
I fear that your reasoning for why you endorse Hillary and not Trump doesn't really speak to someone who likes Trump in the first place. Calling Trump racist, for instance, isn't going to flip anyone's voting bit.
The only very cogent Hillary endorsement (or rather Not-Trump endorsement) I've read that would actually speak to conservatives is this one: http://slatestarcodex.com/2016/09/28/ssc-endorses-clinton-jo...
Which is fairly long and not the kind of thing I'd suggest sharing with your Grandma or Thiel, but I think you could distill more convincing talking points from it that would appeal to people much more conservative than yourself.
Note: My own opinion is too wordy for the small margins here, I'm just relaying sentiments of people I've talked to. I'm from New Hampshire, and people here, especially up north, have had Trump signs from very early on in this campaign, way before anyone in the media seemed to take him seriously.
