This thing about LGBT Rights is nothing to do with Rights - their (LGBT) Rights, as is the Rights of the Disabled or People of a different Race or Colour or Old People, are established in LAW.
The arguments now are about Demanding Respect. I don't believe any group justifies Respect simply because they are Gay, Muslim, Tory or Socialist. The notion of Respect is a personal thing. I have utter contempt for, for example, Peter Tatchell, but I also have utter contempt for Mathew Parris, both are gay but of different politics. My contempt for them is not because they are Gay - I have contempt for them because of the way they think and their sneering sense of moral superiority.
You can't demand Respect, you have to earn Respect, and you're not likely to get my Respect if you generally talk rubbish and think in a rubbish sort of way or you're generally condescending.
The minorites argument is no longer about Rights it is about compelling acceptance (thereby outlawing anti-immigrant sentiment) and Respect (thereby outlawing contempt for Islam or buggery) no matter what your personal views might be. There are a good number of Religous Minorities whose Rights are being ridden over Roughshood simply to accommodate the Demand for Respect from other Minorities.
Gay Rights, and Rights for Other Minorities, nowadays is about Gay Privilege and Other Minorities Privilege, nothing more nothing less.
