I guess that you are referring to Daniel Sysoev that was killed in 2009 and had a dispute with the Old Believers ru.wikipedia.org/wiki/%D0%A1%D1%8B%D1%81%D0%BE%D0%B5%D0%B2,_%D0%94%D0%B0%D0%BD%D0%B8%D0%B8%D0%BB_%D0%90%D0%BB%D0%B5%D0%BA%D1%81%D0%B5%D0%B5%D0%B2%D0%B8%D1%87 He was not an ROC authority either.
The rant about Africa is off topic.
What is discussed is if Orthodox Christianity and Islam are based on identical humanistic values.
Africa is relevant because Orthodoxy is often described as something backward. Islam is undisputedly backward. The example was to portray that the brutality of Islam somehow has humanistic values behind it although these values protected in un-Christian way.
Adultery is perfectly relevant as well for the very same reason.
