I realize the threats you cited are all plausible scenarios for large-scale attacks, but I fail to see the personal threat. If my birthday, gender or relationship status were accidentally shared with strangers, I would not care in the slightest. If it was truly personal, I would never have published it on Facebook, even if I trusted their <i> privacy policy</i>.
