It's not a false dichotomy at all. The choice in this national election, like basically all national elections preceding it, is between the two major party candidates.
Since that's the reality, any actions you're taking regarding the election and its discussion can be correctly regarded as support for one candidate or the other.
So I ask you again, is derping to help get Trump elected moral or ethical?
Your intent is also clear, which is why you spin in circles to not declare it outright.
As far as your overall "who cares?" line of questioning or "why should we care?" about Taylor Swift endorsing Kamala Harris...apparently you care, deeply, which is why you're here in this thread advocating against Harris.
The only false dichotomy in this thread is that we cannot care about both "winning" and the "wisdom and agency of others" (whatever the fuck that means).
