If you subscribe to the idea that politics is a straight line, then for you there is a far right and a far left separated by the great central plains of minor differences. This separation is distinguished by the singular outcome of either the right or left establishing a system of governance that is diametrically opposite. The far left would be characterised by the abolition of private property, primarily, privacy and the complete subservience of the population to the pursuit of a commonly held good, excluding those that didn't hold the 'good will' dear. The far-right would exclude those it feared/hated, primarily, abolish/co-opt private property and privacy and attempt to ensure that the population pursued a centrally directed good. It depends where and what the emphasis of political priority falls upon that allows others to define.
Here is where the idea of politics being a straight line breaks down: the realisation that extremists, be they religious, political or just deranged are merely fanatics intent on the violent overthrow of the state. The outcomes of which are fairly certain, and are almost identical. The end result of political revolution has been seen throughout history, Stalin, The Khemer Rouge, Hitler, Mao et al. It is the outcome that should define what type of label is handed to the politics of a tribe. In the UK the BNP is continually referred to as the far-right, yet their policies drip with socialist nationalization, their descriptive is based upon one policy, not all. Yet they should be referred to as an a extremist political party; with no left or right far or otherwise prefixed. The same goes for the SWP, ANL, UAF who are all extremist groups.
The idea that you can break politics into closely defined neighbourhoods with certain areas juxtaposed is a purposely confusing message. Politics is the pursuit of power by representatives of parts of society. Within that society there are outliers who trend to extremist positions. The outcomes are all the same, a rule of centralized power characterized by extreme violence and a fear of the unknown. It is neither left nor right it is merely an expression of hatred of the individual.
