There is no reason a white father should hesitate to tell his daughters what sort of young men are approved and what sort are not, regardless of what his criteria might be. And he should do so without any fear of "losing her", because in the end, a girl is going to either decide to respect her father's wishes or she is going to follow her hormones. It's always her call... but she can't possibly respect her father's wishes if she doesn't even know what they are.
