That was hundreds of years ago.
Jews more recently experienced Nazi Germany, and still managed to go on to college, get married, and then have children. And they did that without benefit of Affirmative Action.
You are part of the problem - making excuses for blacks who have multiple children with multiple men.
How are blacks who have been born over the last 100+ years having to adapt to a different culture? The blacks in NY who grew up with my parents in the 1940s were part of the same culture.
Conversely, the poor, immigrant Jews who arrived on these shores via Ellis Island were from a totally different culture - and they didn’t even speak English! Still, a generation later, their kids were all responsible, successful adults - most married and living in the suburbs.
Like I said, you leftists are making things worse for blacks by making excuses. You should instead be encouraging them to model their behavior after other persecuted minorities who are successful. Asians would be another example.
