You are pretty optimistic that most know the recent history of law reform.
I don't like euphemisms but I ask an American for the location of "the rest room" not because I want a little nap. Stateside, asking for the toilet can get a bit of a shocked reaction and water closet and lavatory elicits a bit of puzzlement.
I regard "gay" used in relational to "homosexual" as I regard "loo", "rest room" or "bathroom" in relation to a lavatory or latrine. It is a term with accepted local currency.
