My advice is to relax and manage your own life according to God's word. Let God take care of the rest. Do your best to maintain goodness and civility within the sphere of your personal influence.
I'd take the article's point a step further. Many people walking around with free-floating anger and dissatisfaction with their lives are looking for a "cause" to join as a means of focusing their emotions and venting. I think a lot of this gay activism is just that. Once it's no longer a cause célèbre, it will lose it's attractiveness to those not truly affected or interested. Many people are joiners; need to be part of a tribe, ANY tribe, as long as it's cool. Take away the coolness, they drop away.
