The charities Mavar and Footsteps work closely with ex Chadisim who are considered "off the derech". One of the people we work closely with is Dr Alexandra Stein who is pretty fundamental in research around cults. The reason we work so closely with her and recommend our members asosociate with her work and events is because so many people who are clasified as OTD do feel as if they have left a cult and have many commonalities with those who have been in cults that you would agree are cults.
The reason people argue against Chadisim being a cult is the lack of one clear leader. However, the dependency on a Rabbi to "interpret" the scripture and apply it to every day life, as well as make determinations about what is right, wrong, good or bad, appoints individual Rabbis and other community elders as these leaders. The fact that they might not all agree reinforces their singular control over their specific congregation. You need to speak to your Rabbi for them to make a subjective decision on how you should proceed based on how they were taught to interpret the scripture.
The answer we settle for is that Chasidic communities are definitely a cult for at least some of the people in it. Particularly those who want out.
They are confined. They are confined to areas, schools and communuties which permit one to live in accordance with the customs and values of ultra orthodox Judaism. For example, today, many Chassidic communities need an eruv, schools within walking distance and the ability to shop kosher without needing to go too far from home. You cannot just live anywhere in the UK in 2026 and feasibly live halachically as you are dependent on the community. You are even dependent on a Gentile community who are understanding and permissive and help you adhere to your way of life in a modern world. You need a "Shabbos goy" in various forms.
Coercion is rife. The threat of losing your family and friends as well as your closeness to God unless you submit to the teachings is coercion.
Trafficking also occurs. Young men who are barely educated are shipped to join their equally young wives across the country or globe. Young couples are sent away for the young man to "study". None of this is with informed consent. It is coercion.
The people who leave are often isolated and ostracised with poor employment or academic prospects, which is why our charity exists. You cannot leave and still receive recongition and belonging from the community. You cannot leave a Chassidic community and send your children to a Chasidic school. You can fully denounce the existence of God, live where you want and send your child to a Jewish school. Judaism is not a cult.
Chasidim arent raised Jewish with equal access to education and information and then, as adults, choose to become Chasidic. In fact, people who have taken that journey (Baal Teshuva) are seen as inferior by many Chasidim. The ideal is that you were born into it and know no differently.
I see that you want to convert. For the people who have experienced the perils of Chassidic communities, it can be very frustrating when other Jewish people are oblivious or minimise the reality of ultra-orthodox communities for those who want to leave them.
