Would the Daily Mail website fall foul of the online porn filters it has championed?

Ban this sick filth. No, not THIS sick filth, obviously.

David Cameron wants to block online porn, the Daily Mail reported approvingly this morning.

 

Now comes the big question: where the line should be drawn. If you're too lax, things slip through the filter; if you're too strict, non-pornographic images or sites get caught in the net. How do you tell what's pornographic and what isn't? "I know it when I see it," said Justice Potter Stewart in 1964. But it isn't that simple.

Despite the best efforts of programmers everywhere, you can't just tell a computer "block any page with an image or video of a female nipple or male or female genitalia" (a rule which, itself, would be hopelessly over-strict; farewell Titian! So long, Leonardo!). Instead, most blocking software uses contextual clues on the page to work out whether the site itself is problematic. That can be obvious: there are few safe-for-work sites which use the phrase "double penetration", for instance. Except this site, now – which explains part of the issue.

Existing filters show that if you want to make the blocking comprehensive, some of the contextual clues used have to be broad enough to make collateral damage certain. Blocking anatomical terms like "vagina" or "anus", for instance, frequently leads to sites discussing sexual health or feminist topics being caught up.

Meanwhile, humans - being cleverer than filters - learn to use terms which can't be blocked because they also have innocuous uses. (Take, at the extreme end, the use of "Lolita" to denote images of child abuse.)

The thing is, even if all the technological quirks were worked out, drawing the line is still hard, just in terms of choosing how prudish we as a nation are. So where do we start blocking?

Pictures of women in their underwear?

 

 

Sexual, nude but non-explicit photos?

 

 

Pictures of women with clearly visible breasts?

 

 

Topless pictures of prostitutes in 1940s Paris?

 

 

Playboy style photo-shoots?

 

 

Non-explicit pictures of people having sex?

 

 

Well, would you want your children seeing that kind of material? Ban this sick filth.

How the Lib Dems learned to love all-women shortlists

Yes, the sitting Lib Dem MPs are mostly white, middle-aged middle class men. But the party's not taking any chances. 

I can’t tell you who’ll be the Lib Dem candidate in Southport on 8 June, but I do know one thing about them. As they’re replacing a sitting Lib Dem (John Pugh is retiring) - they’ll be female.

The same is true in many of our top 20 target seats, including places like Lewes (Kelly-Marie Blundell), Yeovil (Daisy Benson), Thornbury and Yate (Clare Young), and Sutton and Cheam (Amna Ahmad). There was air punching in Lib Dem offices all over the country on Tuesday when it was announced Jo Swinson was standing again in East Dunbartonshire.

And while every current Lib Dem constituency MP will get showered with love and attention in the campaign, one will get rather more attention than most - it’s no coincidence that Tim Farron’s first stop of the campaign was in Richmond Park, standing side by side with Sarah Olney.

How so?

Because the party membership took a long look at itself after the 2015 election - and a rather longer look at the eight white, middle-aged middle class men (sorry chaps) who now formed the Parliamentary party and said - "we’ve really got to sort this out".

And so after decades of prevarication, we put a policy in place to deliberately increase the diversity of candidates.

Quietly, over the last two years, the Liberal Democrats have been putting candidates into place in key target constituencies . There were more than 300 in total before this week’s general election call, and many of them have been there for a year or more. And they’ve been selected under new procedures adopted at Lib Dem Spring Conference in 2016, designed to deliberately promote the diversity of candidates in winnable seats

This includes mandating all-women shortlists when selecting candidates who are replacing sitting MPs, similar rules in our strongest electoral regions. In our top 10 per cent of constituencies, there is a requirement that at least two candidates are shortlisted from underrepresented groups on every list. We became the first party to reserve spaces on the shortlists of winnable seats for underrepresented candidates including women, BAME, LGBT+ and disabled candidates

It’s not going to be perfect - the hugely welcome return of Lib Dem grandees like Vince Cable, Ed Davey and Julian Huppert to their old stomping grounds will strengthen the party but not our gender imbalance. But excluding those former MPs coming back to the fray, every top 20 target constituency bar one has to date selected a female candidate.

Equality (together with liberty and community) is one of the three key values framed in the preamble to the Lib Dem constitution. It’s a relief that after this election, the Liberal Democratic party in the Commons will reflect that aspiration rather better than it has done in the past.
