The French government,has taken upon itself, to warn people of the dangers of sectes/cults.
They direct people to relevent literature exposing dangers.
There are works cited from ex jehovahs witnesses, some of which have been pursued in justice by the WT$, until now without success, I believe.
Here is the link to the list of possibly "dangerous" sectes, in the view of the government:
http://www.info-sectes.org/masques/sectes.htm
and the page ( in French) on the beliefs of Jehovahs witnesses.
http://www.info-sectes.org/tj/index.htm
There is a link explaining, rather well, the psychology used by the JWs and how to combat it.
This is considered, by French people, rather like the warnings on a packet of cigarettes.
Afterwards, you smoke if you want to. Its up to you. But at least you have been warned.
The sects do not like this information, and take legal action, crying abuse of freedom etc.
Its a normal reaction.But as ex-jws, we would agree that the information given is indeed correct.
