Twenty years ago there used to be not so many blacks and Asians in local
government or on TV as newsreaders; now it is very common. The culture
of these people is becoming more and more part of British lifestyle. But
can we say that racism has become a fact of the past or does it still
exist? The British National Party (BNP), an extreme right-wing group is
supported by about 4% of the population. The leaders of the party say
that they are a respectable party wanting to "preserve the future of
Britain by sending ethnic minorities back to the country they came
from." But their deeds speak louder than their words. The BNP's members
take part in attacks on Asian people. They and their supporters (of
which there are about 20,000) claim that the blacks and Asians are
stealing their jobs. But black and Asian people are two and a half times
more likely to be unemployed than whites. At the same time, there are a
lot of Asians and blacks in medicine and law. The only way they are
stealing white people's jobs is by getting better qualifications. As the
British law allows all British citizens to get their education free,
blacks and Asians get these job places in a fair competition with
whites. Many blacks and Asians were invited to Britain after the Second
World War and in the 1950s and 60s when Britain needed working hands.
Immigrants were prepared to do the jobs white people did not want. The
BNP's idea of repatriation sounds especially strange if you remember
that blacks and Asians are just as British as any other citizens of the
country because most of them were born in the UK. It is natural that
this problem worries British teenagers and they feel strongly about it.
This is what some black and Asian teens said about racism. D h a r a: I
feel half British, half Indian, torn between the two cultures. J a s k i
r a n: I don't think I could ever live in India. I can't speak Punjabi
very well and I feel like an outsider there. S h e r i d a n: About ten
years ago people threw bottles at my uncle because he was dating a white
girl. D u n j h a i s e: I don't think the BNP will get into power
because Britain is so multi-cultural and I don't think the population
will support them. They don't make me angry. I just think they're
stupid.
