Envy and prejudice
People will always attach themselves to something. If one doesn't do this, one feels insecure. A person will attach oneself to a particular identity to keep thwarting this insecurity. This attachment is applied to a wide range of activities that this identity encompasses.
One of the attachments a person will go for is a political ideology. Again, this is done a lot of the time to fulfil one's insecurity and ego rather than any firm beliefs... A political ideology, a lot of the time, is basically a gross generalisation of what you are. You might have a lot of tendencies, but these will rarely manifest themselves as they are prevented by this ideology and belief. There will always be fights and arguments, and a political group will always be polarised because there is a disagreement due to an individal's lack of conformity and relation to the identity.
No matter how sophisticated or philistine, a social group generally works on the same level: its members attach themselves to it and identifies itself with it. The personality of the individual is rarely recognised in favour of generalisations of what symbolises what. People's true thoughts are often repressed to conform to this social gathering. The school playground is a microcosmic example of everything social groups represent: a multitude divided into separate parts were the true individual is left aside due his negligence to identify himself with the prevailing norm.
Envy and prejudice
When someone is part of an identity that person will either envy other social groups or have feelings of prejudice over people they consider to be inferior to themselves. Prejudice is a feeling of wrongly preconceived notions people have wrongly deduced about another person due to their identity. Because an identity symbolises and carries an aura of someone, the other person will often have feelings of hatred against this identity - not the person itself. This can often be racial or related to religion or several other reasons.
People often think that their musical preferences are a true representation of what they are. This is especially true in the playground: the subdivided groups are often there because of the sounds that groups opt for rather than a similarity between the individuals. Also, music is also prostituted as a visual rather than auditory experience, and people will identify themselves with the visual aura of whatever product.
Identities can often lead to extremes. This is often evident in fascism, where people will exert a strong feel of hatred over a group because their identity is inexplicably repulsive to them. Extremes in the social spectrum are examples of how people will attach themselves to an identity because their malicious anger cannot be exerted in any other way: if it isn't exerted via this identity, they feel insecure and unfulfilled.
One of the main reasons I have these thoughts is because I don't have an identity. I don't have a nationality, and I have been often ostracized from social groups. I am neither Chilean nor British, and I refuse to subject my thoughts to either left-wing right-wing politics. Since childhood I have been solitary and have even found the comforting categorisation of 'loner' disagreeable and inapplicable. My lack of identity is what often causes many dilemmas for me, and brings me many confrontations...
