It may be a challenge to see where the sociologist is coming from, but potentially still worth the effort.
As an exJW once said to me: "there is arsenic in the honey".
I imagine it is quite likely that a sociologist (who talks about all religions being cults) would know of Steven Hassan, and if not would appreciate knowing of/about him and his books/website. Maybe a gift from Bookdepository.co.uk (what about the chapter on "Dual Identities" in "Releasing the bonds")?
The cultic or abusive elements of power, control, authoritarianism, peer-pressure, group think, interposing hierarchy and surreptitious clergy class between God and man (as pseudo-mediators) are present in every religion, albeit to varying degrees.
Captives are blinded to the aberrance of their particular group, which has some sort of monopoly on truth which is generally understood to be doctrinal (and not related to Jesus/Messiah/Isa and the gospel of grace).
Some like the WBTS will claim they have no clergy class, and yet there will be a small group of humans prescribing to the sheeple what to think, say and do, on pain of some form of punishment or loss.
It doesn't matter how you chop and dice it religion is always deleterious of the gospel/bissar/injeel/injil - by design and not by accident.
Just ask any Christian/Jew/Muslim to explain what the gospel/bissar/injeel/injil is in one word.
What would you think of a car salesman that had no idea a Ford is a motorcar?
It is religion that prevents people from being what they claim to be - Christian/Jew/Muslim.
It is religion that instead turns people into Churchianists/Zionists/Islamists.
It is religion that deceives its followers into believing that the term faithS is scriptural. The term does not appear in the Judeo-Christian-Muslim scriptures - not even once.
Religion steals our faith and spirituality and substitutes it with religion falsely labelled as faith & spirituality. That is why whilst under the influence of religion we confuse faith with religious belief.
Since when is religion a fruit of the Holy Spirit?
