Langevin's paradox.
The Langevin paradox is a very serious criticism against the theory of
relativity.

Langvin's paradox is another name of the "twin paradox".
In 1911 Langevin gave an example of said "paradox".

 
Yes, but the French are often excessively chauvinistic.

 
Lengrand (aka Hachel) is. A quite ridiculous one. Most French
are not, obviously (look at the election results :-) )

What makes you believe that the French left and the centre
are not chauvinistic?

Nothing is to be taken seriously
unless a French name can be tagged onto it.

 
Fact it that the twin paradox has been pointed out first
by the French communist Paul Langevin, who was very close
with the French/Polish twice nobel prize winner Marie Curie.

Not really, it is already explicitly in Einstein 1905.
Langevin merely invented a more dramatic hypothetical example.

And more not really, Langevin was in the first place an anti-fascist.
He didn't become a communist party member until 1944,
shortly before his death in 1946.

Even in France, I would say especially in France, the absurd
theory that Einstein plagiarized Poincaré has been debunked
strongly.

There never was any basis for that beyond anti-Einstein sentiment.
Idem for the Lorentz-plagiarising,
