I'm also French, aaaaand, I don't particularly like those jokes about us being cowards, but still, I don't mind. I mean, everyone is treated the same (tout le monde en prend pour sa pomme, pour son grade).
Chill out. Okay, it's tiring, I agree. But I actually like the intelligence behind this one in a way. It was clever, well done. So yeah, I smiled. Or maybe I'm just not so patriotic. Dunno. Whatever.
And I don't agree, not all the French people are aggressive. Maybe it's the way we talk. Old people are ***s tho. But with everyone actually. Anyway.
I just have to say that no, we are not cowards :) We have a lot of history, and yeah, our government surrendered to Germany back in 1940. BUT, within the country, we saved as many life as we could with the Resistance, or just because we were against the occupation. Of course there were some people happy with the situation, but we saw that in any other country. ANYWAY.
