Is it normal to think it's okay for men to take a stance on abortion?
Abortion. The sensible stance is to allow a woman to choose. The theocratic stance is to ban it. And the completely moronic yet increasingly common stance is to tell a man he isn't allowed to have a view on it because he doesn't have a uterus.
Telling someone they can't have a view on something that doesn't directly affect them is extremely shortsighted. Are people not allowed to have a view on civil rights atrocities that go on in other countries because they don't live there? Are people without disabilities not allowed to have an opinion on the GOP blocking a bill in 2012 that would ban discrimination against disabled people? Are people not allowed to be appalled by police unfairly targeting minorities if they're white? The line of thinking commonly brought up in response to abortion leads to downright psychopathy. Being able to discern that something's wrong in a situation isn't a matter of being a victim of it, it's a matter of decency. And as for the inverse, women can be anti-abortion too.
People must stand together and see themselves as one if they want to move past the problems that keep so many groups down. That means sexism is EVERYONE'S problem. Every time feminists tell men that they can't have a stance on abortion, they enforce an "us vs. them" situation and give fuel to their critics who say feminism is just a guise for modern misandry. Many feminists seem to want it both ways, to exclude men yet to have their compliance. Look, there's no convincing the MRAs that women aren't out to get them, they have something wrong with them and that's a lost cause. But the biggest thing preventing the average man from getting on board with feminism isn't the platform, it's the attitude. Telling men that what they think doesn't matter makes them an enemy, and that behavior is going to set women back as much as patriarchal attitudes have.
