The Gay/Lesbian movement is a visible presence today that looks critically at sexuality. Though same-sex sexuality (like opposite-sex sexuality) is visible throughout human cultures world-wide, throughout time, and has even been proven to exist in virtually every species of animals, it has not been interpreted consistently in its various settings. In some cultures it has been of no consequence and even celebrated, in ours it has been stigmatized to varying degrees up to and including punishment by death. The movement is relatively young as are the terms gay, lesbian, bisexual, etc. that it uses to frame same-sexuality. The movement contests the idea that heterosexuality (also a recent term) is the essential or superior human sexuality.
