Hmm...that's a good question.
I'll take a completely different approach for argument's sake:
Being a feminist does not mean believing that women can do anything and everything they want. We don't believe that being a woman gives a person the right to commit murder, to steal, to rape, etc.
So, if a person truly believes that abortion fits into the same category as those things, then yes, it's very possible. It's just another thing on their list of things that no one should do. If men could have babies, they don't think men should be able to have abortions either.
Of course, that's the point. Since it is a choice that only women encounter, it can't escape being a gender issue. And because this huge difference between men and women exists, there are simply some issues where you can't just use the "complete equality" yardstick.
