Personally - I think the underlying issue which causes such a "difference of opinion" ladies is not "what" some people identify with or what label they would like to use, I think more people (possibly not enough for some) are more liberal these days - it is that throughout the world those people are a "small minority" across the population but it seems to be that their requirements and views are politicised and then acted upon as if they were the majority or the norm. It is the mass imposition of these views on the majority that causes the majority to react and sometimes not in a good way. Just because someone says something doesnt make it true, our world tends to rely on science for a lot of things. Humans like to rely on facts and they use science to prove those facts until the science says otherwise.
Personally, for me it is a science thing. You have your chromosomes and you are either born male or female with the various bits unless you are unfortunate enough to be in the very rare category of "intersex" - without genitals. You may see yourself differently (I know it's not a choice) remove, or add bits, take meds and change your hormonal responses etc but science says you were born male or female according to convention. I think society should be able to accommodate anyone who feels this way or undergoes gender reassignment, but I don't feel that it's right that everything in society should be changed to accommodate those who are the minority and that provision in all areas of life should be made "in case" someone feels that way. Gender neutral toilets and changing rooms and areas where personal space is an issue, so those things being made "inclusive" is therefore something I disagree with, not because of the subject matter just that in terms of world population, there are going to be a huge majority of people this affects and who may be unhappy about it. Some maybe bigoted, some may feel threatened, some may be ambivilent, some may think its a good thing but all those people are still the majority.
I am also extremely concerned with "gender/sexuality issues" and current thinking and behaviour where children and young adults are concerned particularly with the pressure that social media/peer advice can apply to young minds. Before anyone kicks off I feel the same about any form of politics and religion in schools. It think it is the imposition of a very small minority against the majority that causes resentment.
..and Charys I must say that your reaction to the other comments is not helpful. Using insulting words/dismissing people's views and telling them they "dont understand" does not provide any information to increase debate. There is no right or wrong - just different in my view, but I think it is madness to change the majority world to a minority world.
