The main negative effect is religious strife. The Copts are 10% of the population and they suffer constant persecution and discrimination due to their different religion and language. There are also linguistic and cultural tensions since there are also some Berber minorities whose heritage is not acknowledge or respected by the majority of the Arabic population. Finally there is a good amount of racism. Nubians, who are typically black are also discriminated against and are virtually unexistent from mainstream media.
