unpersuadable

But Garland’s goal was not to persuade the unpersuadable.

He was never a councillor and landed the plum Conservative seat of Richmond, in the Yorkshire Dales, without having to try to persuade the unpersuadable in seats glued to their Labour loyalties.

And Batten, one of the people on the front lines of a long, uphill battle to persuade the often unpersuadable, has probably heard most of them.

He fears that people who are hesitant and might be persuaded to get their shots would simply take advantage of exemptions and become unpersuadable as a result.

One could go on accumulating evidence of this sort for the validity of the idea of the Scientific Revolution, but plenty of scholars would remain unpersuaded and unpersuadable.
