Transgender women in sorority life?

[snowflakemom]

First, you need to let us know if your sorority is a local, NPC, NPHC, professional etc. and what country you are in (for the Title IX rule). Otherwise we don't know what guidelines apply.

Second, something in this situation doesn't ring true to me. You had this situation in your sorority AND your 14 year old sister is transgender? Maybe it's just my part of the country but transgender isn't that common in young people.
