There’s a selfish man in the equation too. Men aren’t robots governed by their penises. We have free will and many abandon their children and chase orgasms instead of finding the right woman for a life-long partnership (i.e. marriage).
You’re right about the selfishness of men. There’s plenty of blame to go around.
Unfortunately, of the 2, women bear the brunt of the consequences of unwanted pregnancies. Of course, if ‘something’ is done about it, the yet-to-be-born child bears the ultimate brunt of the selfishness.
