Feminists of Color Have Argued That the Exclusion of Trans

Feminists of color have argued that the exclusion of trans women in women's-only spaces, such as at the Michigan Womyn's Festival, reflects racism. How so?

A) Claims that trans women should be excluded because they do not have the same experiences as cisgender women ignore the fact that women's experiences across racial lines are also very different.
B) The claim that the presence of a penis might be associated with violence for some women ignores the fact that white skin might be associated with violence for some women
C) These exclusions are typically accompanied by other explicitly racist policies.
D) Both a. and b. are correct.
