This is a faithless age: the Big Problem is the apostates, not the religious

However it may have been in earlier eras, nowadays and for several generations the problem of evil is one of apostates, not the religious. 

This seems so obvious that I am surprised it needs saying, let alone arguing - but it does. 

Both atheists and the traditionalist-orthodox Christians are very keen to pin the blame for "the world, now" on religion: 

The atheists blame religion-per-se - as when they say that the cause of most wars, or cruelty, is "religion". 

While among the religious the blame is fixed upon some-other-religion (usually one or both of the major monotheisms), or else on heretics of their own denomination (e.g. for Roman Catholics - Protestantism, and vice versa - or some particular variant such as Mormonism).  

But a little thought and attention would reveal that nearly always the grouping who support and promote evil are apostates - either those who have explicitly abandoned their religion, those en route to abandonment; or those whose religion is superficial and feeble, and whose affiliation is essentially non-religious (i.e. to race, ethnicity, nation etc).  

I am not-at-all saying that "religion" (in general or particular) is blameless for evil in the world today; but that this is a faithless age in which the religious conviction, hence impulse, is weaker than at any point in world history.   

Religious explanations of the present evil are therefore secondary and relatively superficial.  

NOTE: I do not regard Satanism as A Religion, since it is opposition to God and divine creation. To take the side of the devil and demons is very common, and near-universal among the Western/ Globalist ruling classes - but this is a negative definition. Evil is ultimately opposed to all religion, although evil will expediently use any religion - as it will use any ideology but especially that of Leftism - to oppose God and creation.
