The Queer movement has a large number of faces, races, identities, and sets of problems/controversies that we face.
What is your #1 issue when it comes to Queer politics, and why? I will list a couple of big ones but please don't feel limited to those select few, obviously different sub-sets and communities within the broader LGBTQIA umbrella have their own set of issues and agendas.
Some popular issues: Marriage Equality, Adoption Rights, Immigration Equality, Employment Non-Discrimination, Trans-Inclusivity, (Queer Positive) Safe-Sex Ed, Repeal of Don't Ask Don't Tell Policy, Intersex Genital Mutilation, Hate Crimes, HIV/AIDS, Domestic Violence.
