It was just clumsy attempt to quickly give you the idea based on
cartoonish comparison which could hurt within the given
context someone´s feelings for which I am sorry.

It obviously does not mean that everybody who post
own picture or have facebook is postmodern whack,
but quite often those two match to extend which is
somehow subconsciously intelligible to anyone.
So it is up to you to judge.

You can give million examples why such
notion is utopian, but is it really that utopian
to ask for some Macedonian generals/elite troops
to resemble Alexander the Great, or that face of
Seleucid FMs would be based on original rulers,
as we know them from coins etc., same with
Rome FMs and for rest of them.
