Another case I think this applies is football. Every-one can play football, but not every-one can play professional football. People are just born with the talent of being able to play, for example "David Beckham" or "Wayne Rooney" are both very talented football players. They train daily for hours. Yet if I were to train daily for twice the amount of time as they did, I could garuntee I would still never be as talented as them. So I feel that every-one should be given a chance to play football, but this is not essentially a right to play professionally.
Places where I think every-one should be treated equally are schools. Ever-one has the right to learn, whether or not the are intelligent or slightly slow. Every-one should be treated equally and should be given the chance to the same opportunities. This is why uniforms are used in most schools in the United Kingdom as pupils are seen as equal to eachother.
Also work places, every-one should be treated in an equal way. If there are 2 people doing the same job, but one has a speaking disablity, I think they should both still be paid the same wage. If there was a male and a female doing the same job, then a higher position became available, I think it should be offered to both the male, and the female.
Christians believe that every-one is equal. They believe every-one was created in the image of God. (galations). Most christians believe that all types of racism or prejudice is wrong, yet small christian groups have formed like the kkk, and try to encourage racism. Christian followers such as Martin Luther King and Desmond Tutu used Christianity to help fight Racism. Christians may fight racism in different ways, but many use non-violent protests, or non-violent forms of stopping racism.
Sexism is like racism, but instead it is about gender. If a lady is turned down from a job, yet a man with lower grades than her gets it, this may be seen as sexist. Not all Christians believe that every-one is equal. In churches woman are not aloud to do certain jobs, as this is against the bible. The church encourages sexism in Deuteronomy as it tells of how a man can rape a woman, and then marry her. It also says a man can divorce his wife, yet she can't divorce him, not even in the case of adultery!!!
Yet in galations 3.28 it says "Jews are equal to gentiles as man is to women". This discourages sexism. Despite this the catholic church accepts olnl men as candidates for preisthood because Jesus' disciples were all men and that has been a tradition.
