deviant

unacceptable when used to describe human beings or their behavior. Although behavior may deviate from some statistical norm for human activity, it's an oddity of our perspective that we pick and choose whom to label: we do not routinely refer to murderers or terrorists as deviants, but so label lesbians, gay men, bisexuals, and others. Once labeled deviants, individuals become stigmatized, censured, and penalized. See also dysfunctional.
