When humanity looks at ourselves without labels and just as great spirits, we will shed the "isms" (sexism, racism, etc.) and the persecutions that come with them.
A man sees things from a different light and has to fight for what he believes in. Is he wrong for not wanting to belong or is the real wrong the way that others treat him? Is the man weird, strange, different or is he unique?
Weird, strange, different and unique are all different shades of the same word. How you perceive an experience or individual will determine which shade of this word you use. Another's perception may be entirely different.
