The majority of the world lives in poverty. Parts of the world enjoy wealth that millions will never come close to experiencing. This disparity has created huge incentives for people from poorer regions to migrate into wealthier countries, legally or illegally. This is leading to race and ethnic conflict on a global scale: Germans against Turks in Germany, French against North Africans in France, whites against Mexicans in the US and so on. There are racists that truly believe in the supremacy of race and ethnicity, but these individuals are not the reason for increase in societal conflict. The rise of racial and ethnic tensions is due to economic catastrophe.
This video, made a few years back, revealed the emergence of violent Neo-Nazis in Russia. This video is disturbing and can make the viewer feel angry. It would be misleading to watch this and assume the root to this violence is Hitler and his contemporary followers. There will always be Nazis and other various forms of racists (all of which are not violent). However, their ideas only have mass influence in crisis.
Another hero to some in Russia is Stalin. Not because he was Communist, but a strong leader that brought order and international respect to Russia. In a world of uncertainty and turmoil "stabilizers" from the past will always seem like a panacea to current troubles. That is why it is important for the Left to not get caught up in obsession with "deviant" groups. It is understood, we must take on thugs as they come. Lest we forget, the greatest thugs are the architects of the neo-liberal capitalist world order. This video shows what comes about in countries under their control. The ruling class prefer violence to be horizontal, not vertical.
