People of the Greek Island of Lesbos [wiki], the original Lesbians, are suing gay organizations from using the term "lesbian" to mean a homosexual woman:
The man spearheading the case, publisher Dimitris Lambrou, claims that international dominance of the word in its sexual context violates the human rights of the islanders, and disgraces them around the world.
He says it causes daily problems to the social life of Lesbos's inhabitants.
By the way, the word "lesbian" is derived from the erotic poems of the ancient Greek poet Sappho [wiki], who was born around in the 7th Century BC in the island of Lesbos.
