I think if somebody enrolls as a woman, they ought to be allowed to finish their degree.
Same for vice/versa with a mens college.
If they wish to re-enroll as a different gender, I think they should respect the school's rules on this.
If they are a gender segregated school, they are a gender segregated school.
But I don't think somebody should be asked to leave simply because they came out.
I think they should be allowed to finish their degree with special accommodation for those circumstances.
