The premise is simple and most of us agree with it - you don't desert your country to go and help another destroy it.
Will the decision be made as easily here? Seems not, sadly. Taylor is already talking of life in prison if he's allowed back.
He's also doing what most of them appear to be doing. He wasn't a fighter per se. Isn't it amazing how many of them wandered off to join the battle, and yet didn't actually do any battling. What did they have? A large camp full of onlookers? A cheer squad?
The only sad part about all this is the naivety and stupidity that so many seem to suffer from. Taylor claims he was a bit hot headed, and he's sorry for causing too much trouble.
Do you think he'd be quite as humbled if the war was actually getting won from his side of things?
One of these fighters missed his mum, pasties, and Doctor Who. It's sort of pathetic.
Was this a caliphate of mummies' boys who thought they were being a bit gung-ho. Was it a pub dare? Some of them seem stupid enough to have been those sort of victims.
So what does Ardern do? You know what she wants to do. Helen Clark has already tweeted about Begum, saying you can't leave a person stateless.
Well actually you can, you just have to want to, and Britain has. Let them rot in Syria, where they so willingly chose to go.
Oh, you'll incur the wrath of the United Nations. But what would you rather have, a wagging finger or a crazed jihadist who's vowed to annihilate you, in the prison down the road, with knowing this country sadly, a not unreasonable chance of parole for good behaviour?
You know that Ardern would let him in, you know she's driven by UN-type doctrines. She'd probably put him on the job-seeker benefit and tell him to take his time looking for work.
Javid has started the international response well, America has done similar things, but is facing the inevitable legal challenges.
If there is a weak socialist link here it is, sadly, us. We won't have the same resolve, we won't, I don't think, even want to have the same resolve.
So Mark Taylor, jihadist and traitor, you want him back? And what are you going to say when Ardern says he's welcome home?
