While the creation of “other” groups can have many negative effects on how we see the world today, this trend is in our human nature. The other group builds a greater connection between people within our group. Without a global other, our nation would divide itself into others as well, whether that be democrats vs Republicans, east vs west, etc. The other will either be found within, or outside our society.
To try and eliminate or limit the effects of the other’s negative perceptions is an admirable goal. To be aware of what we as a society are doing to another group, we can attempt to mitigate it’s effect on our perception of the other. However, this is never ending battle, as one other is accepted in our group, another will be separated. Humans will always find a way to alienate others, it’s an unavoidable human truth.
