That things are fundamentally created unequal is the most obvious reality of nature: In my eyes one of the most easily discernible things from nature is that nearly all things are unequal. Living things are not only created unequal but constantly strive to be unequal all the time (think 'evolution'). This includes the fact that some living things are human beings, some are animals, birds etc etc. Some people are born healthy, some have retardation of growth, some cant hear or speak, some can run very fast at the age of 7, then there are 9 year old drug addicts, people who fail 2nd standard, rich people, poor people, atheists, liberals, conservatives, birds that can fly, animals that cannot, trees that bear fruit, mammals, eggs, reptiles, calm people, angry people, short people, fat people, tall people, people with vision problems, diabetics, ophans. If there is one thing we can be sure about. It is the fact that there is a inherent and natural inequality that exists and that we all accept as nature. Try telling a person who touts their belief in equality that all human beings are created with equal 'intelligence' or equal 'intellectual horsepower' and they will make a u-turn like you have never believed. If you really want to anger them tell them everyone is equally 'lucky'.
Equality of Outcome is Nonsense: This is almost common sense. However, for many many issues people feel a sense of fairness only when there is equality of outcome. People don't realize equality or *feel* the presence of equality when there is only equality in opportunity. A slightly facetious example would be the 'spiritual but not religious' nut jobs who claim puke-worthy things that 'all gods are equal' or 'all forms of prayer or equal'. They will not *feel* the presence of equality if I selected only 1 form of prayer/god and followed just that. They would think I am a fundamentalist. And they wouldn't change their opinion unless they see 'equality in outcome'. I am virulently against 'equality of outcome'. Primarily because I am not a communist. I don't want all the 5 runners in a 100m race to win Gold or all applicants to a job interview be given job offers. That doesn't make me a bigot or a biased person. I am a bigot if I move the "starting point" in below diagram (Image Credit: wikipedia.org) leftwards. People should have an opportunity to take a 'shot' at the outcome they so desire. But I strongly disagree with the people who move the "ending point" leftwards and align it with "starting point" (Example: It is one of the flaws of caste based reservation systems in India - which involves a variant of this approach). Sounds like common sense but pretty much every second or third argument that uses 'equality' does this.
p.s2: On a lighter note - The entire intensity of iyengar-iyer god worship debate would be lot less intense if people grokked this.
p.s3: if you give everyone equal outcomes as default - you are not liberal, fair or good. You are actually a bad and unfair person. The whole notion of Satvik and rajo/tamas concept is based on this.
