When we think of stereotypes we think of general stereotypes like “asians are smart”, “blacks are thieves” or “irish are alcoholics” (I’m sorry if this insults somebody, but it’s a fact that those are stereotypes built years ago and well-known around the world). In the end, it’s impossible for that to be truth as we’re all different people. Are you the same as “your kind”? There’s no kind, We are just born as we are.
This racism thing has been around since… always! And I hate it. But I have to say that there is a reason behind all that. Several, actually. The historic reason is that thousand of years ago groups were formed, and with time those group differentiated themselves from others and some rivalry started. With centuries we begin to talk about civilizations. Wars are mostly caused by this, or something derived from it. People don’t like “others”, and sometimes that turns into hate.
