Millenial Jews date out around 50%, if you think AAs have angst, read some of the Jewish magazines like Forward who are questioning what Jews will look like in a couple of generations. Only a fragment of those interreligious kids have any Jewish identification (religious or ethnic). America is a melting point (to an extent) and we only avoided it for so long.
Tbh, I don't see interracial marriage for AAs nationally going above 35-40% or so because that is what it is in Europe and Canada. For all you Coli Negroes hating on me for saying we should accept biracial people as Black if they want to identify as such, this is a good reason right here. In Europe and Canada where this is no such identification people with one Black parent marry a non-Black usually about 80% of the time.
