You've made about ~8 points which would take longer to address than I currently have to spare. I suggest you read 'Black Family in Slavery and Freedom' as well as Booker T. Washington and Thomas Sowell's work. Their scholarship is infinitely greater than any summary I could provide.

Very true, same ideology was/is prevalent among the lower class in certain parts of England. (See Theodore Dalrymple)

Read 'Black Family in Slavery and Freedom' by Gutman.

There are many metrics by which the black family is doing worse now than it was during slavery. E.g. Teenage pregnancy and female headed households have gone up, with a large spike from the 1960s. Black teenage unemployment was also lower than white teenage unemployment for several years in the 40s.

It can be debated what impact slavery has had, but slavery cannot be blamed for the reversal of these key trends.
