Translation of "Zealous" in French

I was religiously zealous, I was certain

un fervent croyant, sûr de moi,

Zealous Algerians believe that by attacking peaceful Kabyle militants they are defending the honor of indivisible Algeria, but in fact, they are only supporting a politico-mafia and Islamo-fascist dictatorship.

Les Algériens zélés croient qu'en attaquant les militants kabyles pacifiques défendent l'honneur de l'Algérie indivisible, mais en fait, ils ne font que soutenir une mafia politique et une dictature islamo-fasciste.

It is astonishing to witness that the Iranians, onto whom the Arabs imposed Islam through military defeat, have become its most zealous followers to the point of oppressing those of Zoroastrianism, though it is the religion of their own fathers. A kind of Stockholm syndrome on the national scale.

Il est étonnant de constater que les Iraniens, auxquels les Arabes ont imposé l'Islam en les battant militairement, sont devenus ses plus zélés adeptes au point d'opprimer ceux du Zoroastrisme, qui est pourtant la religion de leurs propres pères. Une sorte de syndrome de Stockholm à l'échelle nationale.
