A Prospective who hates females

[wanabe]

As a freshman, I use to hang out with this girl, whom we will call "Mary." Myself, Mary and a few other girls were inseparable. We shared secrets as most freshman do when they first get to college, and I learned that she and I both wanted to join the same organization And by coincidence, we were both legacies of this organization. Later on in the year I learned that she had some previous problems in high school with female friends...and she directly stated that she Hated females. She tried to explain that she doesn't mind hanging out with other girls, but due to the distress that these previous friends had on her life, she continued to say how much she really hated females, and how she doesn't consider anyone at her present university a 'true friend.' So of course I was upset to hear, that after spending a year with this girl, I was just an acquaintance. Now we are sophomores, and a couple of weeks ago she had the audacity to give a public speech (for a grade) in her Oral Communications class about how shady females were, etc. However, Mary still wants to pledge this spring! And my thing is...even though I don't hang around her as much, I fear that she might actually make line. Ladies, have you ever been in this situation before? How do I explain that sisterhood is apart of being in a Soroity. Or should i even bother?
