Yeah ! It is certainly a larger question about African presidents leaving office. A black(low-race) US president if in power "without self-deception" can naturally raise a larger."question" about African presidents leaving office AS PER SOCIOLOGY. Social psychology says about respecting "class heredity" in profession(mind)(law). If you don't respect your heredity(whether low or high)(whether donkey or horse),that means you are disrespecting "equating between high class and low class" which will "never lead to everlasting peace(equality)". Our present Indian PM narendra modi is also the finest icon of "dishonour of equating(peace) between high class and low class" which is socially criminal. SOCIAL LAW SAYS THAT TRUE EQUALITY(peace) "PREVAILS" ONLY IF WE ALL HONOUR ITS HIGH CLASS AND ITS LOW CLASS. Isn't it ?
