Here's a translation from Wikipedia:
"Let an impure blood
Water our furrows!
What does this horde of slaves
Of traitors and conspiring kings want?
For whom have these vile chains
These irons, been long prepared? (repeated)
Frenchmen, for us, ah! What outrage
What furious action it must arouse!
It is for us they dare plan
A return to the old slavery!
What! Foreign cohorts!
Would make the law in our homes!
What! These mercenary phalanxes
…(later)
Frenchmen, as magnanimous warriors,
Bear or hold back your blows!
Spare those sorry victims,
For regretfully arming against us (repeated)"
Okay so Frenchmen are magnaminous, valorous warriors. The enemy are the slaves of tyrants. And we're meant to believe the impure blood in a song written by a French revolutionary era freemason refers to the third estate? Seems unlikely to me.
Damn ! it looks like you're right. I fell for this fake interpretation that got spread for the last 10 years on the net, and even reached wikipedia...
Sorry about that.
edit : it's even worst than that, that alternate theory reached the ministry of education and the parlement, since 2006...

Looks like we're having a lot of trouble with the original super barbaric lyrics :)))
But since nationalism was widespread and encouraged in that zeitgeist, and considering the context of a foreign invasion in which the lyrics were written, I am way more inclined to assume that the "impure blood" is that of the "ferocious soldiers" coming for the French.
This is a question that is sometimes very much discussed in France. Always in French : https://www.uneautremarseillaisepourlafrance.fr/blog/2015/12...
Sorry about that.
Did the nobility in any country use to consider the blood of the people they ruled "impure"? Lowborn, sure, but "impure"?
Nobility was calling them impure (since not from noble blood), and they reversed it to something to be proud of (kind of).
