Are you asking:
Is it right that they are homosexual?
Is it right that they are homosexual sorority sisters?
Is it right that they are homosexual sorority sisters in love with each other?
Is it right that they are in love with their soror?
Is it right that others know about it and are questioning their feelings and the appropiateness of said feelings?
At the end of the day, I am not going to question them. I got bigger fish to fry. They are not hurting me any at all.
