Mike, you have a way of twisting reality...

I do not remember who was supporting me,
maybe Mr Gilmour.
If I remember well, an honest summary
was more like:

It seems two different understanding of 1p1v exist.
Some people think that an equal opportunity
for each voter is a valid definition of 1p1v.
Approval for example respects this definition.
It provides different voting power between ballots
but equal opportunity.

I do agree about finding approval "fair" between
voters. But as I said before, there is more to
1p1v than only fairness from the voters point of view.

Fairness has to be respected from the voted point of view too.
In that sense, plurality could be seen as non-respecting 1p1v
when multiple clones come to share the same votes.
In the same way, I have already explained why
I consider Approval not passing the same test.
Approval solves the splitting-vote issue but it cannot
map a bijection between electors and candidates.
So, even if approval is fair to voters, it is unfair to
some candidates (namely the extreme ones, extremeties
being defined according to the small number of alternative
preferences, not according to ideology).

Maybe the "1person-1vote" name is not what you would like
because it does not correspond to the criteria I just explained.
"Reciprocial fairness" might best fit. I do not care about the name,
except if a lot of people see 1p1v as I do. If I remember well,
some people did see things as I do.

PS: I had mail problems, this is why I lost some of
our arguments. If I remember well you did not answer neither:
-the example where approval lost a Condorcet winner.
-my proof attempt that margin and relative margin pass
an extended Ideal Democratic Winner protection from truncation criteria.
-the philosophical point about an extremist governement as an attempt
would benefit more to society than immuability caused by an always
consensual method as approval.Of course this is a matter of proportion,
but the electoral method should not maintain forever the statu quo according

to me. Sometime any extremity would be better than the consensus.
Some methods deny this by construction.
If you prefer to discuss with Donald and Craig, it is your prerogative.
