I don't understand why same-sex couples just don't coin a new term for their union. Why do they have to COPY heterosexual's term?
Would it make it better for you if they spell it "mariage" with one R instead?
Are they allowed to say "sex"? Or should they come up with a different term so that it doesn't affect your pristine idea of what sex should be? Perhaps call it "sexual union". Is that better for you?
