Greek Lesbians Sues Lesbians

Three inhabitants of the Greek island of Lesbos is suing the homosexual and lesbian community of Greece for using the word lesbian to refer to gay women! The argument is that used in it's commonly known sense, the word insults the almost 90,000 island dwellers living on Lesbos, and also known as lesbians.
Lesbos, with an area of about 630 sqaure miles (1630 km), is situated in the Northeastern Aegean Sea.It is the third largest of the Greek islands with a coastline of about 200 miles (320 km).
According to Dmitri Lambrou, one of the three mentioned inhabitants, the islanders have been known by the term for thousands of years, while the term has only been used to refer to gay women for the past few decades.
Lesbian, used in its homosexual sense and used in languages around the world, comes from the poet Sappho, who lived on Lesbos around the 6th century B.C. She wrote many passionate poems about women. However, the use of the word is ambigious in many languages, and can refer to the islanders or gay women.
Funny as this lawsuit is, I'm thinking that even if the Greek courts rule in favor of the islanders, how does one stop the use of a word used in common language around the world?
