Here, the proponents demand, we are either gay or straight. If you think you are a bit of both then you are in conflict with your real self and won't admit to being really gay anyway. Flexible modellers broadly acknowledge sexuality as a many-faceted thing that is not fixed in time, gender or experience. Such sensitive, broadminded souls are quite content to live and let live and happily see sexuality as a spectrum of experience and attraction. Who gives a stuffers basically bonk anything that moves.
Practitioners think any discussion on sexuality is a waste of time and gets in the way of living.
In my apolitical moments I drift into Who gives a stuff mode. I can pretend labels don't count. I can fantasise that the world is a free and easy place in which to do your own thing. But I know the world isn't like that. There is intolerance.
