Culture clash

First of all, I do not know what is a culture clash and I have never hear this term, but the dictionary said that clash is a crash or a type of encounter, so I think that culture clash is like different kind of cultures are in a same place, for example an Indian and a city person living in the same neighborhood, they  live together but they have different behaviors, and  We could see clearly the difference between them, because their forms to live is completely different, so we could say that in a clash culture we can find also disagreement, disputes, and others bad things product of the people’s difference in relation of their culture.

Besides I find a photography that shows a black person and a Nazi person, and it cause me surprise because I cannot understand how people hate each other just because their skin color,  and why the man can hit him in a brutally way. Also we can watch that the man is even capable of killing him, that is horrible and this kind of things should not be happening and less nowadays. Is incredible when we think to what human could do in their nature or “our nature”, is incredible how the human can get to killing someone just for the way of think, the way of wear or just for the color skin that someone have, I think it is an illness.
