The British parliament is on October 11th 2018 going to consider changing the law so anybody could decide to legally change their gender. At the moment if a man wants to fulfill what is called a “legal fiction” whereby they change all of their legal document so that it says that he is a woman he has to have lived as a woman for at least two years and I believe have the support in writing from at least two doctors.
What is being considered is “self-ID” which means a man would not need to be taking hormones or have changed himself physically in any way whatsoever, in other words could be living and acting as a man in the world and would not need the support of any medical professionals but would be able to declare that he is woman and legally be declared so. (This obviously would be the same for a woman who wanted to be a man, but for some reason there are a great deal more men who want to “identify” as being women.)
If this happens it obviously destroys the legal and social definition of what a woman is, the definition is no longer linked to born sex and biology.
This may sound ridiculous and impossible but unfortunately it is very much a very threatening reality.
In fact the transgender ideology has advanced so quickly in the last few years that now trans woman are declaring “transwomen are women” and if you deny it you are shouted down as “transphobic”.
This is happening because people are conflating “gender” and “sex” as categories and saying they are the same. Sex is obviously the biological category to which we belong from conception onwards, I am a woman because of my XX chromosomes which run through all my DNA. Even I was to take male hormones and even have surgery to change my physical appearance to be as male as possible I could never change my sex as that is impossible. Gender is all the traditional ways men and women have behaved in the roles that have grown up around the differences in our biological sex. So people may believe they can change “gender” and be a woman for example be dressing up as and assuming behaviors that have traditionally been associated with a woman in a given society. Clothes, appearance, behaviours and traditions of course still do not change your biological sex.
Well gender theorists are of the opinion that rather than sex being the innate immutable category gender is. So you can “feel” your “gender” and need to the fulfil your understanding of your gender, that’s when you end up with countless categories of “gender” as people try and define and express themselves in terms of “gender” (transgender, genderqueer, non-binary, Demi-boy, Demi-girl etc, ad naseum).
So in other words they divorce gender from biology and gender just becomes a belief in how you define yourself, in fact it is not unlike a “soul” in terms of a live, active, always been present part of yourself.
I am sure you can see this is completely incompatible with Catholic teaching and incompatible with reality and biological fact! The scary part is that this directly threatens women and children. Once a biological man (with all his genitalia intact) can define himself as a woman he has every legal right to enter all “women only” spaces!
