I agree completely, but knowing that the French Revolution laid the foundations for many other radical revolutions over the next few centuries, and considering there have been a few communist movements that were racist/sexist/not as radical as others, I wasn't sure if we wanted to consider them a form of proto-communism.

I still see it as plausible that some french folk came to America post revolution and kept their ideas of "equality," solidarity, and beheading bourgeoisie. But like you said, it was all well before Marx.
