That goes deeper than simple horoscopes. If it wasn't horoscopes, it'd be religion. If not religion, race. If not race, diet. If not diet, hobbies. It's like talking shit about someone because they don't use your favorite distro. Is Linux the problem? Or is it someone's capacity to pass condescending judgements over silly things? Some people are insufferable. That's a people issue.

Back in our early 20s, my friend decided not to date a guy because of his horoscope and some tarot readings she got. You could throw away the love of your life that way.
