There do exist marxist feminists, some of whom are women of color and some of whom do seem to generally share birdman's view of the political process. I'm not sure I could find any quotes of any of them saying that the parties are the same, but you'll find some of them agreeing with the premise that the only way to overcome sexism/misogyny is to overthrow capitalism, or favoring more radical political movements. Note that I don't think that saying such people exists settles any argument.
As an example of a feminist of color who is both anti-capitalist and interesting to read: I'd suggest bell hooks, who writes on the intersection of race, gender, and class. Her views are certainly informed by Marxism, although I'm not actually sure if she identifies as Marxist specifically. She is perhaps
a bit more nuanced than birdman in this thread.
