Nowadays Euclidean geometry is -defined- as that kind of geometry
in which the Pythagorean theorem holds.

A forteriori, it -defines- Euclidean geometry, nowadays.

The Pythagoras theorem is just that. Euclidean geometry is defined by
axioms or self-evident and unquestionable truths upon which all theorems
are derived. Not the other way around.

No, it is not a matter of taste. It is invincible deductive logic and
that is not to the taste of those who profit from confusion. That is,
the e=mcc wallahs.

The // axiom-theorem is a case in point.
You can take it as an axiom, and prove Pythagoras,
or you can take Pythagoras, and prove the //-theorem.

No. From axioms you find theorems including P.

Not up to the 70s when they taught Euclid in schools.

There have been lots of attempts to prove it from the other axioms,
until Gauss and others proved that this is a futile excercise,
by showing that it is an independent axiom that you can leave or take.
