The cruel, aggressive intolerance of the trans cult has been on repugnant display since the Supreme Court ruled that biological sex is binary and immutable. In a historic judgment that provoked unhinged fury from the believers in gender fluidity and self-identification, the judges effectively declared that transwomen are not women.

The Supreme Court’s decision was nothing more than common sense. But it is a sign of how badly our political class has lost its moral bearings that the ruling should have been turned into an explosive national controversy, accompanied by a continuing spasm of outrage from the trans lobby. Alternating between victimhood and foul abuse, the leading activists are a bunch of cry bullies who boast of their supposed feminine instincts but who often act in the most crude macho way.

Their hatred for women’s rights campaigners – whom they label TERFs (Trans Exclusionary Radical Feminists) – has shone through their ugly protests. “The only good TERF is a dead TERF”, read one slogan at a London demonstration last week.

The same misogyny could be found in the protestors’ vandalism of the statue in Parliament Square of Millicent Fawcett, the heroic advocate of votes for women and in the vicious personal attacks on the brilliant author and brave opponent of transgender dogma, JK Rowling, including barbaric calls for her to be burned the stake as “a witch”.

The violent, squalid mood is intensified by the creepy notion of entitlement to unrestricted toilet access, reflected in the activists’ mantra: “It’s none of your business where I do my business”. The same arrogance led a group of extremists to mount a grotesque protest at the entrance to a women’s public convenience in an Aberdeen shopping centre with the clear aim of intimidating female customers.

Far more offensive was the exhibition of synchronised public urination during the chaotic trans rally at Westminster last weekend, cheered on by trans micro-celebrity India Willoughby, who urged her online followers “to drink plenty of water”.

The determination to ignore boundaries can also be laced with menace, epitomised in a chilling video made by a heavily-set activist in a wig: “If you try to stop me going into a women’s toilet, it will be the last mistake you ever make.”

The hysterical, undignified and brutish response to the Supreme Court ruling has fulfilled all the worst fears about the trans movement. Its programme is often portrayed as a new liberation struggle after the emancipation of women, ethnic minorities and gay people, but it is nothing of the sort. On the contrary, the advance of its agenda fuels conflict, undermines women’s rights, exploits the vulnerable, makes a mockery of science, and destroys childhood innocence.

This is a profoundly reactionary creed that panders to outdated stereotypes. What does a man actually mean when he says he “feels like a woman?” Tragically the medical establishment has colluded with this development by promulgating the theory that some people are born in “the wrong body” and as a result suffer from the condition known as “gender dysphoria”, though this concept seems to depend more on political and psychiatric fashion than hard evidence.

It is telling that “gender dysphoria” only took off only after medical breakthroughs enabled doctors to undertake gender reassignments. But this involves a glaring contradiction. In the name of public health, the Government aims to stamp out tobacco, combat female genital mutilation, and lower obesity, yet at the same time our medical guardians take the knife to the healthy bodies of young people and pump them with toxic, life-altering drugs.

Another dark form of betrayal lies in the shameful, Orwellian denial of basic truths that do not fit the dogma, like the link between sex crimes and transgenderism. Almost two-thirds of transwomen prisoners, for instance, are sex offenders.

In the same vein, we are solemnly told by the trans-propagandists that a woman can have a penis and a man a cervix. Labour joined in this nonsense under the delusion the trans creed is progressive, but the party’s politicians ended up tying themselves in knots about the definition of womanhood and peddling absurdities such as the assertion that babies are born without sex.

Disgracefully, Labour are now equivocating over the Supreme Court ruling. In the lunatic culture created by the trans doctrine, the judgement was a blast of sanity – which is exactly why the Government does not like it.
