I get that you feel threatened by gay men, or lesbian women, but inherently, all that any moderate and temperate person really wants is to be happy, to be able to walk down the street without being bullied, and to live a life free of the oppressions so many people face.
You, christians, in this day and age, are on the road to being just as oppressed as gay people once were in so many places, and still are. You, just like them, want to be free of it. To live your life, believe your bible and have your faiths and live by them. And you, just like them, should live by those beliefs and choices without the infliction of oppression on anyone else for their beliefs or choices.
What hinders such understanding is the worrying trend of disparity among the people. When is any singular person's culmination of beliefs and life choices a sphere which within another individual can demand change, without also being by proxy willing to submit to the demands of others? IN a fair society, a person must be willing to take just what they give, and I doubt any person here would be willing to be told by others how they must live their lives. So, just as you would ask the freedom of choice to believe as you do and to be treated fairly, so do most people.
There is a tendency of our culture to impose demands on others that are outside the realm of what constitutes a fair compromise. And after all, what is an equal society if not one founded on the compromises that must be undertaken to ensure the liberty of each citizen, not pervading beyond the point of individualism and thereby encroaching on another person's liberty?
What you see as the stigmatizing of religion isn't the intent of the individual gay, lesbian or bisexual person, it is the result of the despot grabbing onto the equal rights movement with both grubby hands and using it as a tool for social disparagement. They belittle the attitude of camaraderie among citizens who, without being obligated by the system to demand others conduct themselves in certain fashions, might in fact remember the forgotten idea of simply living, and letting others live.
