Abuse in same-sex relationships appears to occur with the same frequency as domestic violence in heterosexual relationships, and for the same reasons. The dynamics of domestic violence are similar in both LGBT and heterosexual relationships. According to Barbara Hart in Naming the Violence, "Battered lesbians describe the patterns of violence as terrorism and control. The same elements of hierarchy of power, ownership, entitlement and control exist in lesbian family relationships. Largely this is true because lesbians have also learned that violence works in achieving partner compliance."
The Gay Men's Domestic Violence Project reports that one tactic abusers use is to "try to convince their partners that their abusive behavior is 'normal' or 'normal for a gay (G), bisexual (B) or transgender (T) relationship.' This tactic is especially effective with people who are inexperienced in GBT relationships. Abuse is not normal in any relationship, including GBT relationships. Abuse has no part in a healthy relationship."
The differences surrounding abuse in gay or lesbian and straight relationships have to do with social context. For instance, one threat used by batterers that is unique to same sex abuse is the threat to publicly disclose the partner's sexual identity.
