Is this hypocritical or not?

So this scenario from Chasing Amy made me wonder. Alyssa is a lesbian, meets a man named Holden and falls in love with him. Her lesbian friends ostracize her because she fell in love with a man. What Im wondering is, is it hypocritical of her friends to be upset, when a staple in fighting for gay rights is "one love, equal love, you cant help who you love". I mean if that's really what they're about then it would be unfair of them to judge her for finding love with a man instead of a woman. If this situation were real, is that how real-world lesbians would react?
