I'm a scientist.
There are more than two sexes. There are people who have two XX chromosomes and a Y.
There are humans with three XXX
There are humans with extra chromosome material in their cells - (trisomy) down syndrome people for example.
She's 100% right... sex is not binary.
I still favour separate women's facilities and abhor the erosion of any gender's rights in favour of anothers'.
I would like to see trans, and easy access disabled toilets for example, as well as those for men and women.
Ideally every swimming pool, and public toilet would have a family room / multisex change rooms, and toddler toilets as well.
Banging on about how you have no respect for a scientist as she has burst your binary bubble argument for women only facilities is really pathetic, and shows your ignorance of what science is all about.
Science has a very clear understanding about how genes work, and how they're not expressed the same even within the same organism - there are many truncations and mutations, and epigenetic effects can cause genes to make proteins which in other circs wouldn't be made. For example you can have many different types of genes within an organism... chimerism for example, or non human bacterial genes and RNA expressed - mitochondria are an example of this. That's before we get into the millions of non human cells in the gut, and how they influence behaviour.
Just because you want all women toilets to remain all women, (which I agree with) does not mean you can pick and choose your own facts to support that wish.
Science is factually based, and above opinions!
Alice Roberts has my 100% support a a scientist.
If you can't get your head around that we live in a soup of genetic material then I suggest you google genetics of the human organism and see for yourself how right she is.
The sad reality of most people is that they gave up science in school and went to study something farcical in college like post modernist media studies which does nothing at all for the individual, the world, or society.
I applaud her worthy attempts to educate non-scientists to the facts of life.
