Racism

Yesterday my mum went to a meeting and told me of this couple she spoke to, or someone who knew this couple, i can't remember. This couple lives along West Coast highway and are white, and they have adopted three black children, two aboriginal and one jamaican. the oldest son (who's an aborignal) just turned 19 and is the sweetest, nicest, very meek and mild-mannered child they have. the second is an aborignal girl (who's apparently not very nice) and the third is a ten yr old jamaican.
Recently the oldest celebrated his 19th birthday, just down the road from where they lived. After the night he walked home and his friend offered him a lift but he declined as he was nearly at his house anyway. While walking home five english teenagers who have just moved to Perth, (three boys and two girls, one who was just expelled from st marys) got out of their car and threated him with a screw driver and asked him to fight them. When he refused they beat him up and ran over him with their car. He was killed on his 19th birthday.
I felt a lot of anger and i actually cried when i heard this. Why are people so racist, that the hatred inside causes them to kill a fellow human being? Didn't these teenagers feel any sense of guilt or thought what they were doing was wrong? Why did they kill him?
This family had experienced racism throughout their lives. Once when the 10 yr old jamaican was at Karrinyup shopping centre with his white cousin, a man drove past them with his wife and two kids in the car, and he wound down his window and spat at the boy.
Also when these children were young their white adopted mother used to push them around in prams and people in shopping centres would spit at her too.
They say Australia is a multicultural country. This is true in a sense there is a diversity in cultures but that doesn't mean they are all accepted. I never realised the extent of racism and how prevalent it is in our everyday lives. Although come to think about it, people were racist to me in school when i first came to the country, but lately i haven't had any personal encounters with racism, or maybe i just don't notice them?
Why is there so much hatred in this world? Why are people racist?
I love what Marian (rianm.blogspot.com) did on her free dress day. She took a stand against racism and wore a shirt with anti-racist slogans written on them (hope she has pics on her blog).
Racism is everywhere and needs to be abolished! although in this world there will always be
racist people. Why can't everyone accept everyone?
I guess everything comes down to people needing God's love. Everyone has God's love, he loves everyone but they need to know it's there and accept it, and allow his love to manefest in them so that they may love others as well. Thank God for his love.
Any thoughts or opinions on racism please let me know.
