I fully understand and respect that some people genuinely feel they were born to the wrong biological sex.
I recently spent three hours interviewing Caitlyn Jenner for my Life Stories show and came away massively impressed by her extraordinary courage and determination in transitioning from all-American male Olympic gold medal hero Bruce Jenner to a woman.
This is not something anyone does lightly and those who do it should be treated with full rights, respect and equality.
But what I don't support is the creeping eradication of conventional gender altogether, as if somehow it is a bad thing.
This new gender war is being driven by the radical transgender community, which - like radical feminism to non-radical feminism - is a very different, far more aggressive, loud and extreme group to the non-radical transgender community.
They basically want anyone, including very young children at school, to be free to identify how the hell they like, and their campaign has been undeniably successful.
That's why Facebook currently provides over 70 different gender 'options', from 'two-spirit person' to 'neutrois' and 'transmasculine'. One is simply: 'neither'.
Now, I don't care if adults want to identify themselves as giraffes or parrots if it makes them happy. That is their right, so long as they abide by the laws of the land.
But I do care when massive pressure is applied on the rest of us to stop using words like 'boys' and 'girls' because it may offend the gender fluid brigade.
I also care that kids as young as five are being encouraged to embark on a journey to change their gender and/or sex before they even really know what either of things even mean.
Anyone who's had children knows they go through all kinds of confusing emotional turmoil before, during and after puberty.
Why add to that confusion by making them think that 'boys' and 'girls' are offensive terms?
There are so many obvious unresolved problems with this surging transgender activism.
Some schools have begun eliminating gender distinction in their sports programmes, so any boy who feels he's a girl can play on the girls' team. This obviously puts most female athletes at an immediate physical disadvantage.
Other schools now allow boys who identify as girls (apologies to anyone offended by those words…obviously) to use the female bathrooms.
How can that do anything but create huge unease and discomfort?
Companies are being bullied and harangued into converting to non-gender-specific merchandise lest they get branded 'trans bigots' on social media. We see it in our high street stores and on our TV commercials.
The problem gets even more acute when we consider sexual offenders in prison.
Already, we are getting cases of male rapists identifying as female so they can switch to female prisons. It doesn't take a genius to work out why they may want to do that.
So self gender identity is a very complex and potentially very dangerous thing.
We're told this this is the new civil rights movement, that gender is the newskin colour.
But is it?
What does the word 'gender' even mean?
Well, check any dictionary and it will provide a simple answer something like this: 'The state of being male or female.'
Therefore we are all either boys or girls, men or women.
If, on reaching adulthood, someone like Caitlyn Jenner reaches an informed, mature and unchanging belief that they were born to the wrong sex, then I will be the first to offer respect and encouragement for them to transition and fight for them to have equal rights.
But until then, for God's sake enough of this madness.
Let our boys be boys, and our girls be girls.
