Take a gander at this photograph of a porky protester screeching 'Nazi scum!' at a Donald Trump supporter in London this week.

It's uncanny how much she looks like the Baby Trump blimp being flown at the same demonstration.

This priceless resemblance was spotted by a wag on an internet forum called ARRSE, which is an abbreviation of the Army Rumour Service, popular with those interested in military matters.

At the demo, she sported a bottle blonde hairdo. On her Twitter profile, her hair is purple, she's got glitter glued to her cheeks and she's posing in the middle of a circle of EU stars

Laugh? I almost spilled my milkshake. The woman in question answers to the name of Siobhan Prigent, although her friends on Twitter know her as @SiobhanGrrArgh.

She describes herself as an 'Intersectional Feminist, LGBT+, accused crazy cat lady, body positive, striving for equality. Trying to educate myself daily. TERFS & SWERFS not welcome.'

Intersectional Feminist? Sorry, can't help, I'm afraid. Accused crazy cat lady? Pass. Body positive? Judge for yourself, but I imagine it involves finding excuses for being fat.

TERFS & SWERFS? Now then, I have heard of TERFS, although I'm not sure what it stands for.

They're women who get into fights with 'trans' folk because they insist, somewhat controversially, that people born with penises shouldn't be allowed to describe themselves as female, or use women's toilets, changing rooms and swimming pools.

But SWERFS? Your guess is as good as mine. Maybe they're lady Smurfs. Where are they all coming from?

Trump's detractors laugh at his idiosyncratic hairstyle and orange complexion. So what are we to make of @Siobhan GrrArgh's appearance?

At the demo, she sported a bottle blonde hairdo. On her Twitter profile, her hair is purple, she's got glitter glued to her cheeks and she's posing in the middle of a circle of EU stars.

Yesterday's Mail featured another picture of her with green hair, some kind of star inked onto her face and what looks like an engagement ring through her nose.

Apparently, she also has a tattoo of Groot, a tree-like superhero from the Marvel comics, on her arm. Of course she does.

So I wasn't surprised to learn that, by her own admission, she's had 'Borderline Personality Disorder' in the past.

In the normal course of events, we'd never have heard of @SiobhanGrrArgh. She only came to our attention after she joined the anti-Trump rally at Westminster.

Elsewhere in the crowd, another grey-haired Trump supporter was attacked and knocked to the ground by the self-righteous mob.

People with proper, productive jobs can't afford to take time off work to throw milkshakes and wave banners in the middle of the afternoon. It turns out that @Siobhan GrrArgh does have a job. And this is where it gets even better. A stock image of the protest is pictured above

If the man in the MAGA hat hadn't been abused and showered with milkshake, we would never have given @SiobhanGrrArgh another thought.

But her overt aggression and contempt for anyone with a different worldview typifies the modern, agitprop Left. It's not enough to agree to disagree, they have to demonise their opponents, to portray them as evil.

The pro-Trump grandad said the event had been reasonably good-natured until she started accusing him of being a Nazi.

It was an unfortunate slur, to say the least, given that Trump's visit was to mark the 75th anniversary of D-Day, to pay tribute to the tens of thousands of brave young men who gave their lives fighting real Nazis. Yet it's the one offensive N-word the Left is happy to throw around, when they're not labelling anyone who disagrees with them as a 'fascist'.

As the Mail said yesterday, haven't any of these morons ever read a history book?

This kind of behaviour might be understandable, if not forgivable, in an over-excited teenager. But @SiobhanGrrArgh is 34 years old, for heaven's sake, an age at which she really should have grown up.

What is striking is how many of the demonstrators were not in the first flush of youth.

The bloke standing next to @SiobhanGrrArgh, shouting at the pro-Trump grandad, has a grey beard and is wearing a cloth cap. A pound to a penny, most of them work in the public sector, or were on official trades union duties. That's if they're not on the dole.

People with proper, productive jobs can't afford to take time off work to throw milkshakes and wave banners in the middle of the afternoon.

It turns out that @Siobhan GrrArgh does have a job. And this is where it gets even better. She runs a private company which provides 'clinical services' to the NHS. Yet here she was on a demonstration against, among other things, a free trade deal with the U.S., which opponents claim will lead to the privatisation of the health service.

You couldn't make it up. Still, self-awareness is not one of the Left's more obvious traits.

If ITV ever decide to make a sequel to Love Island, they should invite @SiobhanGrrArgh to take part. She could go round hollering 'Nazi scum!' at the other contestants until she was voted off.

They could call it Hate Island.

Until then, @Siobhan GrrArgh has gone to the top of the leaderboard in this year's Here We Go Looby Loo Awards. It will take an extra-special madwoman to pip her to the title. The bookies have already stopped taking bets.

To be fair, she has had the decency to apologise belatedly for her behaviour and has closed all her social media accounts.

No such apology has been received from the star of the show, the Labour leader O.J. Corbyn, who chose to address the demo, after turning down an invitation to the state banquet.

The man who would be Prime Minister preferred the company of the rabble flinging milkshakes, screaming 'Nazi scum!' and attacking middle-aged Trump supporters, to dining with the Queen and the President of our closest ally.

Like @SiobhanGrrArgh, Corbyn has never grown up. And he's twice her age. He's an unreconstructed student agitator, utterly unfit for the highest office.

At least she admits to having had a personality disorder. What's Corbyn's excuse?

Years ago, my son, who was then about 13, asked me: 'Dad, can dogs be gay?' He had noticed our lab Ossie's tendency to mount anything that moved, even other male dogs.

Not so much gay, as not fussy, I explained as best I could. To be honest, I've never given the sexual proclivities of animals a second thought until now. But a new TV programme claims same-sex action is commonplace among our four-legged friends.

One in 12 sheep are said to be homosexual. How do they know? To find out, a ram was put in a pen with 30 ewes in season. But he wasn't interested and instead kept trying to get at other rams in a separate enclosure.

The head of a sheep-breeding firm said 'you see ram-on-ram behaviour going on' all the time. Will we get Dorset Horns and Leicester Longwools on the next Pride March?

I suppose that they could always call in Ann Widdecombe's gay conversion therapists.

Seriously, though, farmers are worried that if rams refuse to mate in large numbers, there'll be a shortage of lamb and prices at the butcher's will go through the roof.

For once they won't be able to blame it on Brexit.

After being told for years to eat less red meat and more chicken, the so-called experts claim that poultry is just as bad for us as steak.

Researchers have discovered that when it comes to raising cholesterol levels, eating chicken has exactly the same effect as beef. I suppose they could always try dipping it in chlorine.

The new politics didn't last long, did it?

Funniest story of the week was the split in Change UK, a party that was only set up a few months ago.

Six of its 11 MPs have left to sit as independents, leaving just Soubry Loo and a quartet of other sad losers.

Apparently, there was a clash of egos, they couldn't agree on who should be leader and it turns out there wasn't much appetite among voters for a bunch of reheated, EU-mad self-publicists after all.

So no change there, then.
