At least since the Stonewall riots in 1969, people from the greater trans communities have often been politically aligned with the lesbian, gay, and bisexual communities. However, researchers and some activists from the greater trans communities argue trans bashing should be categorized separately from violence committed on the basis of sexual orientation ("gay-bashing"). Anti-trans bias crimes have been conceptually and characteristically distinguished from homophobic crimes in the scholarly research. One argument is that conflating violence against trans peoples with violence against gay people erases the identities of people in the greater trans communities and the truth of what happens to them. However, campaigns against gay bashing and trans bashing are often seen as having a common cause.
