Life or a Clash ?

[Qelic]

I was thinking that , how we just tend to narrow our social choices just because of hidden clashes in ourselves . I mean We all know that
its in human nature to resist or oppose the idea of its peer , that may some how take shape of an imposition ( which we fear ) . So r we this stupid that we are always inclined to tackle others in name of survival , for things that may somehow happen . or do not exist physically ?

as an example I am starting with myself .........

Faith ,

I prefer monothiests over polythiests or idoltorous believers
In monothiests , I prefer jews over christians , Offcourse below Muslim
In Muslim I prefer sunni over shiite
In Sunni i tend to unintentionally discriminate in name of wahabbism

racially ,

I prefer Persians , Afghans or western or north western pakistanis
even among them I prefer persians ,
I prefer turko - persians , ( my own )
I prefer urban and educated

and the list goes on


in every walk of life we have a side to protect or support . Either we jump for man U or Ac milan . Or we support democrats or republicans . this vs that .

Why is that and how much annoyed do u feel by this clash thing ? do u try to avoid it ? or u r one hardcore idealist ?
