@boomerang,
In my opinion, feminism is basically a belief, by men or women, that a woman does not belong, as property, to a male, a race, an ethnic group, but is empowered to be her own person, with whatever goals she prefers to have.
So, the prior century's feeling, by some men, that a male of another race/ethnic group, should not be dating "their women" was antithetical to feminism, since women in those men's eyes were only "their women" (aka, our property).
Similarly, all other women's concerns, from salary equality, to abortion, just are part of the pantheon of issues for a feminist to have an opinion. And, I do not believe it has to be only one opinion, to be a feminist opinion. Meaning, as long as women understand they are not property to be stolen by another tribe, or property to be traded to other families, or property of some male, she is a feminist. Whether a feminist chooses to be a beach bunny in a bikini, or a church lady with long dresses, is just her choice.
Anyway, feminism just falls under the main headline of "women are no one's property."
