I don't know that men's lack of need for abortions or similar things are relevant really. Equality doesn't assume that everyones needs or circumstances are similar. It's equality of respect for the person, not sameness.
However, I would not say that I think feminism is particularly about desire for that kind of equality either. People may believe in equal dignity and respect for all persons, but not see it through the same lens, or talk about the same social structures, or look for the same kinds of solutions. People may have quite a different vision of what that all means.
Femism is a particular viewpoint about women's social and leagal position, why it is the way it is, how it might be bettered, a view on how women relate to men and larger society. It's based on a particular period in time and place, a particular understanding of freedom, of history, of what it means to be oppressed. It developed within a particular social, economic, political, and technological context and often takes that context for granted.
People can disagree with any of those assumptions or sets of foundational beliefs, or come from a place where that context is very different and so gives them a very different lens, without being immoral people.
