"Homophobic people may use mean language and name-calling when they talk about lesbian and gay people. Biphobic people may tell bisexual people that it’s “just for attention,” or that they’re inherently cheaters. In its most extreme forms, homophobia and biphobia can cause people to bully, abuse, and inflict violence on lesbian, gay, and bisexual people."
