I might be wrong but think adultery is criminally illegal in some part of US too. That’s a similiar thing. In Russia adultery is only illegal in the Navy (or maybe not at this point) but that prompts nothing beyond disciplinary action.
That’s purely religious stuff within legal system.
As for Chaplin he is an excentric populist figure and not representative of all things Orthodox.
When it comes to Islam there is Dan Sysoyev who are on the opposite side.
Now I feel like you have appointed me the advocate of the devil but let’s play ths game further.
I personally believe Islam has no place in Europe or Americas but it makes perfect sense in Africa.
Just name some “semi-decent” African country and it is Islamic.
When you have universal poverty and 35 year life expectancy due to 40% HIV rate it makes perfect sense to chop hands and feet off thieves and carjackers and to stone adulterers or throw homosexuals off cliffs too.
It is a matter of human survival.
Please keep on track, adultery is not related to this.
Sure Chaplin has some odd ideas as can be seen here https://vk.com/id352520495
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.
