Is it normal that i strongly dislike cleft chinned women?

I used to have this very mean cleft chinned biology teacher and her brother(also cleft chinned)was my maths teacher, he was very kind unlike his sister. She was very very mean to me and used to criticize every single thing I did, she always dressed in an extravagant way and she was narcissistic and pretentious unlike her brother.I feel that cleft chins are manly. Every time I meat a girl with a chin like her I automatically dislike her, but I find it attractive on men.
