It concerns me that your job has you dealing with child safeguarding, yet you are ever so deeply ill-informed on what intersex and DSD is.
there is biology outside a gender binary
Gender isn't real. It's a man-made misogynistic social construct that relies on stereotypes. Only sex is real. Sex is immutable and it's binary. And actually, even setting aside the physical external differences - with chormosomal abnormalities, intersex or as is more favourable a term now - DSD (Differences of Sexual Development), prove and reinforce the binary nature of sex, as this graph below on DSD chromosomal abnormalities by a Biologist shows.
I also worry for trans people and the rates of violence and suicide in their community.
Trans people (particularly transwomen) have far more power and privilege than everyone else, especially women and girls. Statistical evidence shows they are the safest group out, and have the lowest level of violence, and that there suicide rates - despite suicide being pushed very heavily as a weapon to get parents to trans their children, are no higher than any other group. Unfortunately though if one don't push past all the hyperbole about trans and actually look for facts and evidence, one wouldn't be aware of this, as Suicide Ideation is pushed very heavily.
Trans people aren’t trying to hurt you.
Some aren't, that's true. There are some good, decent, grounded trans people that are aware of the reality of their situation. However, too many of them or the activists, go around threatening women with rape, with wire-covered baseball bats, with being knived and bashed, even burned to death (a plot to burn down a building with women meeting inside for a Let Women Speak rally was exposed on twitter, with police then being tagged in). At no stage in history have women been more at risk of violence and abuse. Just for speaking out about our basic human rights and needs.
and pee in peace
If all they want is to pee in peace (which is what WOMEN AND GIRLS WANT, too), they can pee in peace in their sex-based facilities that match their sex. It really is that simple.
