I don't argue with it.

I wouldn't argue with a criterion unless it were incompatible with
properties that I consider necessary or important.

My only proposals for official public elections are Approval, and maybe Score.

Some of their properties:

They meet FBC, Later-No-Help, Mono-Add-Top, Participation,
Mono-Add-Plump, Monotonicity, Consistency, IIAC, Voted-Majority, and

The 1st 4 of those criteria aren't met by many methods.

Some of the others, such as Pareto, Monotonicity and Voted-Majority
are met by many methods. I don't consider IIAC to be necessary, but it
still makes sense and has some desirability.

So Bristow's criterion is compatible with the most important
properties, and with the only methods that I advocate for official
public elections.

Though Approval and Score meet that criterion, all Condorcet methods
fail that criterion.
