It makes quite a bit of sense that one of the most oppressed classes of humankind have co-existing conditions.  Many transgender people lean toward ultra masculine or feminine employment to enhance their self-respect and identity.  From what I have seen it does not work and they, as this study points out, have problems with family, work, depression, etc.  What this study indicates, without addressing it directly, is that the non-conforming gender the LGBT community presents is the tip of the iceberg that is gender oppression.  In a deep sense, LGBT issues are women's issues, the unjust and harmful nature of gender as represented by controlling majorities.  And yes I am talking about religion and government.
