I don't know how things are in Scotland, Ake, but in the United States, a person's civil rights can't be denied unless they have been convicted of a crime or have shown that they are mentally incompetent, and / or constitute a danger to themselves or others, in which case, any abridgement of civil rights must be by due process of law and is limited and conditional.

Homosexuality is not a crime, nor is it a sign of mental incompetence or a danger to others.

[Now, before you hop on the AIDS wagon ("constitute a danger to others"), a person can be prosecuted if they knowingly expose another person to AIDS infection—or hepatitis or tuberculosis or any other infectious disease.]
