Your right, I apologize for that, they are not banned....
They are included on a list of cults and are denied f inancing as a recognised religion. Interestingly enough the state subsidies are provided by all taxpayers, including those who profess a non-recognised religion or who do not adhere to any religion or belief system. This system is not equitable in so far as taxpayers are unable to prohibit the state from using their income tax to finance religions and secular humanism that are openly opposed to non-recognised minority religions.
Also, the state has put in place mechanisms and agencies - Parliamentary Enquiry Commission on Sects, Centre for Information and Advice on Harmful Sectarian Organizations and Inter-Ministerial Coordination Agency of Fight against Harmful Sectarian Organizations - to identify so-called ?harmful cults? (bad religions), warn the public and fight against them.
A few more things denied them...
The distribution of printed material, including religious and philosophical writings, is forbidden by municipal decrees in certain parts of Brussels and of other towns: near schools, (Christian) churches (but strangely enough not synagogues, mosques or any other non-Christian places of worship), military barracks, etc. Other regulations provide that any distribution of printed material, even free of charge and on a small scale, may only be carried out with the written approval of the mayor and after the payment of a small fee.
Some Belgian municipalities have made it a requirement for candidates for positions as civil servants to swear a statement that they do not belong to a harmful sectarian organisation.
Renting public places for meetings is often denied to religious associations mentioned on the official list of 189 movements suspected of being ?harmful sectarian organizations?.
In divorce cases, courts sometimes deny the child custody to the parent who is affiliated to a non-recognised religion.
*most of the above was taken from reports already posted*
I guess I just personally have issues with denying people the freedom to practice their religion without being discriminated against, yes even Jehovah's Witnesses. I have no problem with honest informative material being distributed to people so they can make their own judgement calls, but beyond that it's up to the individual to make a decision about how they want to worship.
