hold simultaneously ideas which are not easily reconcilable argues, then, a deep confusion in the Arab public mind, at least about the meaning of democracy. The confusion is, however, understandable since the idea of democracy is quite alien to the mind-set of Islam." A view similar to this that understands Islam and democracy to be incompatible because of seemingly irreconcilable differences between Sharia and democratic ideals is also held by some Islamists. However, within Islam there are ideas held by some that believe Islam and democracy in some form are indeed compatible due to the existence of the concept of shura (meaning consultation) in the Quran. Views such as this have been expressed by various thinkers and political activists in the Middle East. They continue to be the subject of controversy, e.g. at the second Dubai Debates, which debated the question "Can Arab and Islamic values be reconciled with democracy?" Brian Whitaker's 'four major obstacles' Writing on The Guardian website, Brian Whitaker, the paper's Middle East editor, argued that there were four major obstacles to democracy in the region: 'the imperial legacy', 'oil wealth', 'the Arab–Israeli conflict' and ' "militant" Islam'. The imperial legacy includes the borders of the modern states themselves and the existence of significant minorities within the states. Acknowledgment of these differences is frequently suppressed usually in the cause of "national unity" and sometimes to obscure the fact that minority elite is controlling the country. Brian Whitaker argues that this leads to the formation of political parties on ethnic, religious or regional divisions, rather than over policy differences. Voting therefore becomes an assertion of one's identity rather than a real choice. The problem with oil and the wealth it generates is that the states' rulers have the wealth to remain in power, as they can pay off or repress most potential opponents. Brian Whitaker argues that as there is no need for taxation there is less pressure for representation. Furthermore, Western governments require a stable source of oil and are therefore more prone to maintain the status quo, rather than push for reforms which may lead to periods of instability. This can be linked into political economy explanations for the occurrence of authoritarian regimes and lack of democracy in the Middle East, particularly the prevalence of rentier states in the Middle East. A consequence of the lack of taxation that Whitaker talks of in such rentier economies
