Translate the following English sentence to French:
"When, for example, his fellow party members demonstrated in front of Fiat against the owner of the firm, the language used certainly did not lack force, but nobody dared to suggest that the language used during a demonstration had to be suitable for a court reception."
Quand ses camarades de parti ont, par exemple, manifesté contre le patron de Fiat, les mots qu'ils vociféraient n'étaient, certes, pas tendres, mais jamais personne n'a osé dire que, lors d'une manifestation, il fallait utiliser les mots dont on use à un bal de débutantes.
