"It is better to be defeated, in principle, than win on lies" - Arthur Calwell.

2004 Olympic Games, gymnastics, Alexei Nemov ... Do you remember this event?

He was a wonderful person, and, of course, a great athlete! When he took part in this competition, the judges have shown for gave a very low estimate score. All the fans thought that the scores were (here the verbs must agree with each other. Thought is in the past tense so to be must also - hence were not are) not correct. All of the Stadium howled! (Not only the Russian fans). Nemov was trying to reassure his fans ...
There is injustice in the world, not just in sports. You can meet with injustice at work, at university, or on the street ... In other words, it is everywhere. It surrounds us everywhere.
I do not know what you think about this problem. But I can not win the battle unfair. (I am unsure what you mean by this sentence. Perhaps - "I think it is unfair") I think that all people should have equal opportunities and work by the same rules as the other.
Maybe it's silly, but if we compare the theory of Darwin (survival of the fittest), and purely human principles and views on life, it would appear that they contradict each other.If you think about it, then it is not clear how people should behave in the modern world.
According to the theory of the great scientist, we are not obliged to help each other. But! On the other hand, a person has almost a spontaneous reflex ... If someone near you stumbles, your brain instantly reacts to it, and you pull put out your hand to help.
You can compare the company with this behavior to animals or insects. For example, rats and ants. In the colony of rats, survival of the fittest, they do not know how to share, everyone pulls the blanket over himself. While the ants have the remarkable property that both trafilaks, they help each other.
Well, let's not be like "rat"!
Although, if everyone lived by the rules, it would be a bit boring. When you're hurt or you feel that someone has wronged you - smile. I think that makes a person better than injustice, pushing you to the accomplishment of great things, and the embodiment of all of your dreams! =)

Good work! I think you offer excellent advice in your last paragraph.
