We are here to learn. The shouting that you backed in another thread is what can cause negative emotions and even hate. So, are you here to back shouting and negative emotions? According to this question, I think you want peace. Peace can never be if people are shouting at each other. This includes mothers who shout at their kids all the time. The only lesson they are teaching is that shouting is a way of getting what you want. It's selfish, it's not love. 

This question has been asked several times..  It is human instinct to protect what we have and to fight for what we want. Have you ever been upset with someone?? angry?? its one of the most common human emotions, 'survival  of the fittest' .. It's out nature.  People will always fight and protect. look into the animal world, it exists there too, only difference is we have taken it further due to our higher intelligence and have created weapons to do it better.  In a social society we hire (elect) leaders to decide which fight we want to be involved in.  You or anyone else will never succeed in creating that perfect white gown utopia. accept the fact that you are human and you will do what is necessary to fight for what you think is yours as most wars are due to resources.
