I agree that there is a large chunk of Trump supporters that will not be swayed by fact-checking. However that's still a vastly important thing to do because they goal is not to sway those that are unreachable already but rather to sway the chunk that still can be reached. On a larger picture: I regard the fact that a large chunk of people by now seem oblivious to facts and unreachable for civilized dialogue as the threatening streak in the last major votes, see brexit, see the rise of the AFD in germany. The crucial question for the next coming years will in my opinion be how we can enter a reasonable discourse with people that see every statement as a bipartisan issue that must be decided on principle, regard all measured statements as lies and political correctness and are unwilling to compromise on anything. We live in interesting times indeed.
