Caitlyn Jenner is not attaching herself to the historical struggles of women and the experience of growing up in a sexist world. She's not attaching herself to being discouraged from male-dominated fields. At least to my knowledge.

Rachel IS. She's attaching herself to the struggles of having African hair in a society that judges it. Attaching herself to the experience of being a victim of hate crime. Attaching herself to the experience of growing up in a racist world.

That difference is good enough for me to accept one and not the other. And I feel intellectually consistent in doing so.
