Nice! I only corrected your gramatical mistakes as its a subjective topic where I do not want to assume that what I think you wrote is what I think you mean. For example "When we hear some words we should think about them in other ways. Maybe you can find something different", this sentences on their own do not really make sense, but in this context what I think from this sentance is that there are many people in the world with different upbringings and experiences and that depending upon their circumstances they may say or have opinions that do not match with your own, but by understanding this it is possible to mutually agree on each others' existence as "good people" and not resort to violence or anger and try to resolve disputes with understanding and discussion.
