I don't need to explain the Pregnancy Police for you to know exactly the kind of people I'm talking about. Sometimes it's worth going a little more in-depth, though. Specifically, I want to point out the signs you've accidentally joined the pregnancy police, because from where I stand, I feel as though it's kind of like joining a cult: you don't always know what you've gotten yourself into before you're in really deep.
You don't necessarily need to experience pregnancy to be a member of the pregnancy police (though most have at some point). You don't even need to be especially interesting in pregnancy, birth, or parenthood (though most usually are). You just need to have opinions. Like, lots and lots of opinions. Oh, and you need to think those opinions are The Right Opinions. Most importantly of all, you have to voice those opinions loudly and insistently.
A tiny little fraction of me is sympathetic to the plight of the pregnancy police. After all, as a society we're told pretty explicitly that treating women's bodies as objects for public enjoyment, judgement, and consumption is perfectly acceptable. My sympathy is extremely limited, though, because WTF, you guys? Pregnancy Police are all in the Mounted Officer division, and they can barely see a damn thing from atop those high horses.
