All other contraceptive methods also have serious failure modes having nothing to do with personal irresponsibility. For example, you can get pregnant if you have alcohol while you're on the pill. This is something doctors often don't tell you (women pass the info around on the internet). Or you can have sex and then get the flu, in which case presto you can get pregnant. Or your antibiotics can interact poorly with your contraceptives (again... not usually covered). This is only one method... there's issues like this for all of them.
Once again: why do you persist on arguing about topics you know nothing about?
Here's the thing. If you break your arm, even doing something really stupid and risky, we don't just say "hey, you're stupid." We do what's best for you and set your arm. And if you have two children while being unable to support a third because economic downturn, we don't make you carry that child to term. It's not like there's no cost to being pregnant and giving birth. There's a huge cost to it, physical, mental, financial. And it's not like there's no cost to being put up for adoption. There's a big cost to it. We can eliminate all those costs simultaneously, or we can say "Hey, you were stupid. I'm just going to make a whole bunch of people suffer because why not."
Because you know who has a lot of sex? Married couples. And you know who really, really,
really doesn't want to get pregnant--and is the person getting an abortion in the US some 50% of the time? Someone who is already struggling to feed a family.
Unless you're suggesting abstinence during marriage, in which case, well, okay player :3
The part where you imply that you know
anything is the part where you seem to think you're qualified to discuss this topic and are telling people "no, it has nothing to do with bodily autonomy and everything to do with morality." What this says to me is that you understand nothing whatsoever about what is at stake, and every comment you've made so far has only made me more and more certain. You don't understand periods, you don't understand birth control, you don't understand women's health clinics, and you don't understand the circumstances under which people usually seek abortion or why "being stupid" is usually not the problem.
Still, it's easy to not get pregnant. You have to make some choices at some point to lead up to you being pregnant, vast majority of the time.
It's true that you could just choose to have gay sex. That is a really good birth control method.
