"Even mass immigration from the Third World?" I asked rather naively.
Of course, was the emphatic response. Think about how much better formerly homogenous countries are now they're colourful and diverse!
Well, over the past couple of years I like to think I've done my bit to chronicle the many diverse opportunities Western countries and peoples have been on the receiving end of; they just keep on coming, however, and we had two more notable cases come to light very recently.
Firstly, in the United States, 19 year old Somali Mohamed Osman Mohamud was detained for plotting to bomb a Christmas tree lighting event in Oregon, hoping to kill as many people as possible.
Mohamud, who the BBC naturally describe as a "US teenager", had apparently been dreaming of carrying out Jihad since the age of 15:
Somalia's loss was clearly America's gain - think how boring Oregon must have been before fanatical barbarians who dream of slaughtering those they live off were imported. It doesn't bear thinking about.
Mr Mohamud, who lives in the town of Corvallis, had driven a van to the ceremony and was arrested at around 1740 local time on Friday (0040 GMT Saturday), about 20 minutes before the tree lighting was to occur.
Prosecutors said Mr Mohamud had shouted "Allahu Akbar!" (God is great!) and tried to kick agents as they closed in.
Court documents said the case began in August 2009 with e-mail exchanges between Mr Mohamud and his alleged associate in Pakistan's North-West Frontier Province.
Special FBI agent Arthur Balizan said: "The threat was very real. Our investigation shows that Mohamud was absolutely committed to carrying out an attack on a very grand scale. I want to reassure the people of this community that, at every turn, we denied him the ability to actually carry out the attack."
The Oregonian newspaper quoted Oregon US Attorney Dwight Holton as saying: "This defendant's chilling determination is a stark reminder that there are people - even here in Oregon - who are determined to kill Americans."
He said there was "no reason to believe there is any continuing threat arising from this case".
An undercover agent had posed as an associate of the Pakistan contact and met Mr Mohamud to discuss the plan, the court papers said.
The agent informed Mr Mohamud there would be "a lot of children" at the ceremony but Mr Mohamud allegedly said he was looking for a "huge mass that will be attacked in their own element with their families celebrating the holidays".
Mr Mohamud allegedly told the FBI agent that he had been thinking of carrying out a jihad, or holy war, against infidels since the age of 15.
There will be plenty of people wondering how this could have happened - and the answer "America imported lots of aggressive, unassimilable Muslim aliens from some of the most hostile places on the planet" will never even occur to them.
Lawrence Auster reports that around 99.6 of media reports did not mention the words "Muslim", "Islam" or "Islamic".
Frankly, I'm a little impressed the BBC left in the mention of "Jihad". Their sideline rather grimly informs us that the US is facing an "increasing home grown terror threat" without ever quite alluding to why - although they are probably more inclined to blame the English Defence League rather than suicidal immigration policies.
But still, let's be thankful that the FBI had the opportunity to take down Mohamud before he had the opportunity to give innocent Americans the ultimate payback for their generosity towards him.
Britain is in the same boat, of course. On Thursday, The Guardian reported that some Afghans are spending part of the year working in Britain before spending their holidays fighting NATO troops back home:
Well of course he does - it's a great opportunity, I'm sure, claiming benefits illegally from the infidel before spending a relaxing few weeks trying to spill his blood.
British-based men of Afghan origin are spending months at a time in Afghanistan fighting Nato forces before returning to the UK, the Guardian has learned. They also send money to the Taliban.
A Taliban fighter in Dhani-Ghorri in northern Afghanistan last month told the Guardian he lived most of the time in east London, but came to Afghanistan for three months of the year for combat.
"I work as a minicab driver," said the man, who has the rank of a mid-level Taliban commander. "I make good money there [in the UK], you know. But these people are my friends and my family and it's my duty to come to fight the jihad with them."
"There are many people like me in London," he added. "We collect money for the jihad all year and come and fight if we can."
His older brother, a senior cleric or mawlawi who also fought in Dhani-Ghorri, lives in London as well.
It's about time the West woke up to just who is benefitting from all these opportunities, and who has the most to lose.
