What the US needs is instant runoff (via ranked choice) voting.
Short of that, people with your mindset need to volunteer, fundraise, and vote. Otherwise those parties will never match the scope of the current duopoly.
The downside here is that proportional voting doesn't stand a bat's chance in hell of ever getting enacted because it really would lead to a major upheaval in DC. And the very people that would be 'losing their jobs' are the ones that'd need to work to pass it, which would be a tremendous undertaking. You'd need a 2/3rds majority in both the house and senate to start the process, and then you'd need 38 of the 50 states to ratify the change. And at the end of this process the two major political parties, who are in control of every single major political body in the United States, would have just ceded a tremendous amount of power.
If it were possible to transcend parties and vote just for candidates that represented my nuanced beliefs, I would switch in a heartbeat. Instead I'm forced to prioritize which issues are most important to me, and then plug my nose and vote for the party that best represents just those (even though said party comes with a lot of undesirable baggage).
With a president that openly labels the press the enemy of the people?

It's impossible. Everyone will have their nuanced beliefs and no candidate will match perfectly except in rare circumstances.
With a president that has appointed more 1st/2nd amendment-protecting federal appellate judges than any other president, you mean?
Similarly I presume the rise of Boris Johnson with Brexit is a reflection of the British people, regardless of whether he has his conservative credentials in order.
For a sufficiently loose definition of “reflection”, yes. For a sufficiently tight definition of “reflection”, no.
> does one define American conservatism by reciting a prescription of what people ought be when they say they're conservative
One defines conservatism by a set of values and policies. The same goes for liberalism, fascism, communism, environmentalism, nationalism, etc.
At this point, I'm for just about anything besides FPTP, as long as it has some level of proportional representation.
