When two groups of individuals disagree, rational discourse is the best resolution.
When one of those two groups refuses rational discourse, patience and education is the best resolution.
When that same group begins creating their own “truths” out of whole cloth, and then begins to force those “truths” upon the other group, the only resolution is war.
You cannot negotiate with people who cannot even agree that reality is the same for you as it is for them, that 2+2=4 and not 5, that the Earth goes ’round the Sun and not vice versa.
This is the impasse we have come to. The future will likely be writ by who controls the most bombs and bullets.
