In a democracy, the popular is often the powerful. The majority vote plays a central role in governance, sometimes directly when you elect a specific individual and sometimes less directly when selection of an individual or a course of action is part of a larger political pattern. It's a mistake though to think that the popular vote affords your opinion power in spite of the rights that you claim for yourself.
In a democracy, when you say "I have a right" you proclaim "All have this right". Democracy does not care for conditions, and is blind to our differences where they do not afford special responsibilities.
In a democracy, when you say "I have the right to marry" you proclaim "All have the right to marry". Furthermore when you say "I have the right to marry for love" you proclaim "All have the right to marry for love". A universal right must necessarily be universal. There is no right to determine who's love is legitimate so long as those lovers are of a capacity to make an informed and responsible choice. Choice with regard to the special responsibilities needed to safeguard our young, our vulnerable, our friends, families, sons and daughters.
Your supposed popular opinion does not matter; any right you claim, you claim for us all.
