The Scottish Independence referendum was not "given", it was demanded and enabled by the Scottish electorate voting overwhelmingly for the Scottish National Party.

The 10% you quote is a deliberate lie, the official rate of homosexuals in the population is just over 2%. If the rates dont matter, why lie about them?
Equality is not a dirty word, especially in law....but conventional marriage and homosexual "marriage" are not and will never be equal.
Homosexuals couples are of the same sex, so, incapable of conceiving or bearing their natural children, thus they are also prevented from building an extended natural family structure....both cornerstones of traditional marriage.
The only way is to attempt to re-define the word "marriage" to accomodate a tiny fraction of the 2% of the population who actually wish to use it, to the detriment and concern of hundreds of thousands who are already married or who wish to be conventionally married in the future.
