I don't know why homosexuals commandeered a good old English word for their own use. For modern readers, a lot of literature will mean something totally different to them.
Language, like society, is a living, breathing animal. For people of my grandparents' generation, "wireless" is a completely different means of receiving information to what it is today.
Most people have the ability to manage such nuances when reading, as they have when definitions have been added or changed throughout history. Our of interest, are you as bothered about the right wing commandeering words like "liberal", "cuckold" and "snowflake"?
