Friend keeps making negative comments about my zodiac sign...?

This is kind of weird. So one of my good friends has recently started studying astrology, like she’s taking college courses for it to become a certified astrologer. I didn’t even know that was a thing but it is. Anyway, she has started making negative comments about my zodiac sign. She said she found out a boyfriend she had in high school was a Capricorn, and he was mean to her, so she says that’s the worst zodiac sign. I’m a Capricorn lol. She keeps saying I must be suppressing my abusive tendencies because all Capricorn’s are power hungry and abusive. I’m just like um okay... whatever I guess... I’m just a chill stay at home mom, in what way am I power hungry? 🤣 I don’t really know how to approach this. I tell her I don’t really believe in all that and our personalities are based on genetics and our life experiences but she keeps saying “yeah Capricorn’s and earth signs have trouble believing in anything spiritual. They’re close minded. Sorry.” Like wow do you not see how mean that is to say? I’m honestly considering stopping being friends with her even tho we’ve been friends for 5 years. Wwyd?
