And talking of discussions, let's move to another hot-button issue and the upcoming survey on same-sex marriage.

Where in this example the hair-trigger outrage is coming from the left:

Melbourne streets plastered with homophobic posters ahead of plebiscite Homophobic posters with the slogan "Stop the fags" are circulating on the streets of Melbourne. — 9 Honey, 21 August, 2017

Last week, campaigners for marriage equality were aghast at reports that the City of Melbourne was being papered with a homophobic poster, which claimed that:

92% of children raised by Gay Parents are abused. 51% have depression. 72% are obese. —

There's no doubt it was hateful, offensive and just plain wrong.

But all we had for evidence that it was part of a city-wide hate campaign was this one tweeted picture:

Spotted in Melbourne - Heffernan Lane. How is this for a unity moment? — Twitter, @DanLMcG, 19 August, 2017

Yet, it was soon widely accepted

By Pedestrian.

The Women's Weekly.

The Daily Mail and many others.

That the flyers were everywhere:

'Stop the f*gs': Horrific homophobic posters showing men holding rainbow NOOSES appear in laneways as the country prepares for gay marriage postal vote — Daily Mail, 21 August, 2017

And it was soon dominating the news on TV too:

STEPHEN QUARTERMAIN The Prime Minister has defended the rights of people opposed to same sex marriage to freely voice their views in public. JONATHAN LEA: The latest posters found in Melbourne attacking the safety and health of children raised by gay parents. EM RUSCIANO: So, what are you going to do to protect these vulnerable kids because your respectful debate, with all due respect, is in the toilet. — Channel Nine News, 22 August, 2017

All the media except 10 News used the same photo from the same tweet.

So, given that we'd been assured by some media that the posters were all over Melbourne, had anybody actually checked?

And was there in fact, more than one?

Well not according to the City of Melbourne, who told Media Watch:

A City of Melbourne officer was sent to investigate on Monday morning but did not find the poster ... Our officers were asked to keep a look out for any similar posters but, as yet, have not observed any posted in the municipality. — Email, City of Melbourne, Media Manager, Mandy Frostick, 25 August, 2017

Strangely, that wasn't mentioned in much of the coverage, even though Melbourne City had made it clear.

And as Buzzfeed pointed out, even the original tweeter, who had started the hue and cry, hadn't actually seen the poster in situ:

Leach-McGill revealed it wasn't him who first took the photo, but a friend who snapped it on Thursday night, and sent it to him via text to tweet to the council. — Email, City of Melbourne, Media Manager, Mandy Frostick, 25 August, 2017

So, we had one photo, no posters and no first-hand witnesses. And while we're certainly not suggesting it was all made up, it's pretty clear the media were way out of line in suggesting the posters were all over Melbourne.

Which brings us to 10 News and this photo, which is quite clearly a fake.

As you can see it is remarkably similar to this stock image from Getty, taken by a Spanish photographer, of a bus stop in Europe.

And Ten has just photoshopped the poster into the hole. Naughty, naughty. As Ten explained to Media Watch:

The poster in question had been taken down when our film crew visited the laneway in question so we were forced to source a copy online. Unfortunately, an oversight in briefing our graphics department interstate may have created a false impression about its size and location. This was not a deliberate attempt to mislead our audience, but a creative error which we regret. — Email, Neil Shoebridge, Director of Corporate & Public Communications, Network Ten, 28 August, 2017

And so you should.
