LGBT is broadly defined as an individual with a diversity of sexuality and gender identity. LGBT is an initial that stands for Lesbian, Gay, Bisexual and Transgender. Another two letters were included where letter “Q” stands for "Queer" or "Questioning" and letter “I” represents “intersex”. Sexual minorities are often named as LGBTQI or LGBT+ where “+” emphasis on the spectrums of gender identity and sexual orientation. Beside of your biological sex, gender identity is the gender you preferred and sexual orientation implies your preferences for relationship. As against traditional culture and religion value, sexual minorities are being discriminated and attacked constantly. Their sexual preference was viewed as mental illness and deviance which required forced treatment and violence from professionals and family members to rectify their choices (Almeida, 2009). LGBT members receive unequal rights and treatment in terms of education, employment and other rights due to prejudice of general public and the society ( 林祖偉 , 2018 ; 法政匯思 , 2018 ). LGBT social movements is emerging around the word in the hope of advocating equality of LGBT and LGBT-friendly society. With the constant development of LGBT culture and community, the outcome of LGBT social movement is becoming significant (Fredriksen-Goldsen, 2014). For example, homosexual is no longer classified as crime or mental illnesses. Also, law protection against discrimination were launched and exercised in various countries to ensure LGBT members receive equal rights and treatment. In some countries, same sex marriage is being recognized and these same-sex families earn equal rights to adopt children as other heterosexual families (Thoreson, 2014).
