A lesbian is a female who is sexually attracted to other females. Lesbians have been subject to much discrimination and violence, some youth get kicked out of their homes for coming out to their parents. Some people offer "conversion therapy" but this has been proven to be harmful to the subject. At first, scientists classified lesbians as being mentally ill, although this has been overturned. Many religions prohibit same-sex marriage (although some denominations allow it), and this is the stem for most of the prejudice against lesbians.
