I think where it crosses the line is where we've explicitly made things illegal (such as housing discrimination) due to past bad behavior. I don't think targeting based on race is wrong, per se. BET shouldn't be forced to advertise to white people, a Christian dating site should be allowed to target Christians, etc. But housing is another category altogether and ad targeting based on protected categories should be disallowed. It sounds like Facebook realizes this and called this a "technical error."
