We are just one special case of an issue that everybody faces in some context. Consider some possible approaches to the problem of desire and the price that has to be paid for satisfying it. People of conservative temperament recognize that our relationships with others do count, and that we sunder meaningful relationships at our peril. Transition, and we are very likely to lose them. We all know the terrible pain that might be involved, and not just to ourselves.
Radicals see the whole issue otherwise.
In that perspective freedom has to be seized, or it is not freedom at all. Mere tolerance, bestowed from above, isn't freedom, because what can be given can also be taken back. In between there is the liberal position. Taken to its extreme this says that personal freedom is an absolutely good thing, whatever the consequences. There is no problem at all in extending that position to the freedom to dress as one wants or to alter one's own body as one might choose.
