The simpler the ‘fact’, the more likely it is to be an oversimplification and largely untrue.
In this example, you have to overlook any time someone became pregnant without consent. They never chose it to begin with, so blaming them for “not taking responsibility” for something they never wanted is oversimplifying a complicated subject to the point of falsehood.
It’s also especially funny how often this argument comes from people who, in the same breath, will talk about their savior being “of virgin birth”. You can’t argue that chastity works for everyone when it didn’t work for Mary.
Who becomes pregnant without consent outside of rape victims (which is an entirely low population compared to those with abort for reasons outside of that)? If you have sex voluntarily, you consent to the possibility of pregnancy. So yes, it IS very simple.
