Why do westerns have to have a scapegoat????

like first it was blacks n now its brwns n prob t'll be yllow skinnd people next. what my question is what makes u think tha u re so superior jus cus u have white skin? i mean lik if a brown man is walkin down the street even if hez a well educated, polite man whos not even harmin ne1 jus goin bout his own way then why is it tha d white skinnd steet bum or a white skinnd hoodie on d street that tink tis kewl to hav a go at him nd why dosent ne other good white citizen pin by like to stop tha?? or even if it is a brown man walkin down the street or enterin a public transprt full of white ppl why do u have to give that man the (neg) vibes even though he mite not even be a muslim or nowhere even closely related to any millitant organisation. Ppl come up wid 'they r takin ovr r jobs' hmm but how is tha if ur own electd so calld democratic govt brings em in. 'wat if hes a terrorist' so wat there r n hav bin white terrorists but i dont see this happnin wid all white ppl all round d wrld
