Positive discrimination of disadvantaged groups in employment and education is immoral

What is moral depends on ur moral philosophy. A utilitarian could defensibly argue that discriminating against white ppl in favor of black people to correct a major discrimination-induced wrong like the racial achievement gap is ultimately moral.

Begging The Question

This assumes that a utilitarian would argue such, and you have not explained why correcting such a situation would be a utilitarian goal. Indeed, the opposite might be the case.

Positive discrimination of disadvantaged groups in employment and education is immoral

Existing wrongs and imbalances can not be - in reasonable time - fixed by means of equal opportunities (level playing field). Therefore positive discrimination is a necessary lesser evil.

Begging The Question

This assumes that it is necessary and possible to "fix" such "existing wrongs and imbalances," and that it is necessary or possible to enforce a "level playing field," while leaving such a situation undefined.

Positive discrimination of disadvantaged groups in employment and education is immoral

Positive discrimination is effective in balancing existing inequalities in employment, pay and access to education.

Irrelevant Conclusion

That may or may not be the case, but it does not address the premise that positive discrimination is immoral. You may argue that such effects offset the immorality of positive discrimination, but you have not done so.

Positive discrimination of disadvantaged groups in employment and education is immoral

Disadvantaged groups suffer or have suffered from discrimination within a culture which created inequalities in employment, pay and access to education.

Argument To Pity

This is beside the point of the original premise. If you wish to argue that, because some people are at a disadvantage, positive discrimination is not immoral, you may do so, but you have not done so here.

Positive discrimination of disadvantaged groups in employment and education is immoral

If positive discrimination is indeed immoral, replacing old wrongs with new wrongs is immoral.

Begging The Question

While I agree with the conclusion, this is begging the question, assuming that wrongs cannot be righted by, shall we say, opposite wrongs. Many do not recognize this, and therefore the case needs to be made.
