What is Prejudice?

Prejudice is predjudjing other people by the nationality or religion without getting to know them first. I think its very mean for someone to dislike someone because of his or her religion or nationality. To decide wether you like someone or not you should get to know him or her first. Its bad to have prejudice because it doesnt matter wich skin color the person hasor wich religion he or she is as long as he or she is a nice friend. It doesnt matter what the person is wearing or where he or she was born as long as he or she wants to be your friend. But also once you get to know the person and the person is mean, you have the right to not be his or her friend.
