Domestic Violence happens in same-sex relationships too.
While much of it is very similar to domestic violence in heterosexual relationships, the main differnce is that the abuser can use the victims GLBT indentity as a means of power and control.
Examples:
-The abuser threatens to "out" their partner.
-The abuser derides the victim with anti-gay epithets.
-The abuser tells the partner they are not a "real" GLBT.
