I just don't think that I am the
right person to answer your question. I don't
have enough knowledge of Cuba during this
time, plus I wasn't alive so I don't even
have personal knowledge to draw from. In
general I do think that the "hope" of
an anti-capitalist future, symbolized through
communism and Castro's leadership, were in
line with the political values of progressives
in the US.
However I think that relationship
changed over time, and of course Marxist
and Socialist feminism is less practiced
today than it was then, but those two strands
of feminism are probably the best to research
in looking for context/comparisons.
