Biden's bio says he was born in 1942. He was 31 years old when Roe v. Wade was passed (with 5 out of 6 justices approving it appointed by Republicans, BTW). As he was mourning the recent death of his wife and infant daughter in a car crash at the time, he probably wasn't even thinking about whatever the Supreme Court might be doing or not doing.
I'm close enough in age to Biden that I can tell you honestly that the most warnings we heard about sex in our generation was that we shouldn't wear patent leather shoes or boys could look up your skirt.
I never heard of "the pill" until I was about 13 and my friend, one of three sisters, said, "My mother could die if she had any more children and she and my dad don't care what the Pope thinks."
And I was like, "Too much information--I don't want to think about your parents having sex."
Did Biden learn about loving his neighbor when he was growing up Catholic? I sure hope so.
Biden can probably remember the days when Robert Drinan, SJ was a liberal congressman from Massachusetts. He probably looks around at these new activists bishops and thinks, "Oy, vey! What happened in the past thirty years to change the landscape?"
