It appears to be a meme created by the user johnnywhiterabbit on Youtube, which in turn is the punch line of a mantra he created. It's been flagged as inappropriate meaning people get a warning when trying to watch it, judge for yourself:
The message is clear and in line with 2083, namely that White nations are being subjected to genocidal demographic warfare by means of mass non-white immigration.
The message is non violent, it only addresses a problem, white genocide, though it remains to be seen if even this minor act of defiance will be tolerated on Youtube. If it gains more popularity it will likely be removed.
I've developed a comment screening strategy myself where I only allow pro-Breivik messages to be posted to my videos. This is not in opposition of free speech, but to communicate Commander Breivik's message that it's too late for civil debate, and too late for a democratic solution. An additional benefit is that it really pisses off the Cultural Marxists when they see a screen full of comments in praise of Anders Behring Breivik. Muslims get annoyed as well and leave the occasional comment, I guess they don't like the idea of being deported back to their 2nd world nations that will turn into 3rd world nations once the oil and tourism industries dry up.
The creator appears to originate from Stormfront, an American White Nationalist site with a fairly strong anti-Semitic following. As of 2012 less than 50% of all children born in the USA are white, so their battle against immigration has already been lost, and the US White Nationalist movement has a difficult ideological foundation to work with.
The message of the mantra has also been extended and converted to several catchy music videos.
Ultimately I don't think this mantra will accomplish much as the mantras from the left are accompanied by righteous zeal, anonymous death threats, spitting opponents in the face, and a system that will be indifferent if this behavior comes from the left, and totalitarian when it comes from the right.
As Commander Breivik would say, unless you execute twelve traitors you may as well be screaming your message alone in the woods.
