By saying that it’s not the implication ‘at all’ is pretty arrogant and tone deaf when there is an obvious pushback to these comments from lots of people.
By shifting the conversation to America as a whole, you’re avoiding what was actually said. And if it’s something that goes beyond just the black population, why bring up Jim Crow and how it was better then? Did Jim Crow keep white families together too?
The entire premise and the way t was presented was offensive and stupid.
The logical fallacy that you seem to have taken to heart is thinking that if one points out that black marriage rates and family cohesion were better in the past, it must have been because of Jim Crow. Actually, as has been abundantly show, family formation and cohesion were better in the past because traditional American culture was strongly dedicated to the Christian faith, to family formation, and to personal resilience as an American attribute.
More generally, as Gertrude Himmelfarb and other scholars have shown, Christian morality was the foundation for generations of moral and material progress. To take a prominent example from the American context, for decades in the middle of the 19th Century, Irish immigrants were regarded as the most backward and violent community in New York (think "Gangs of New York"). That changed due to Catholic evangelization led by Fr. John Hughes, who eventually became the Archbishop of New York.
Notably, Hughes established the Catholic school system in New York and its success led to it being copied throughout the country. Within a generation, Hughes and the priests and nuns he recruited and the schools and social services they provided changed the Irish Americans of New York into a solid, church-going working class on their way up in the world. And they did so in a city that at the time regarded the Irish with as much disdain as blacks.
Black Americans today are finding their way up in the world, and in Florida, it is often due to educational voucher programs that Byron Donalds advocated and supported when he was in the Florida Legislature. Black churches, parents, and teachers running small neighborhood schools have done quite a job in Florida in helping boost the test scores of black students.
What now? Will you dissent and tell me that sounds just like Jim Crow, back when Black people ran many of their schools.
