People put JW's in the same category as any religion. That is simply not true and so shouldn't be viewed as such.
The religion or leadership of the religion lies, uses deception, then brainwashes it's followers so they lose themselves and unable to make decisions for themselves.
JW's put a public face that they only study the bible, no human is their leader, they are united in thought because they have the truth, and everybody is free to live their lives how they so choose and it's a worldwide brotherhood of like minded people. People aren't forced into anything and free to come and go as they choose. If that was the case, nobody would have a problem with it.
Instead, they pretend it's that, then once a person is inside they are brainwashed into not doing higher education, cutting off relationships with all nonmembers, not saving or planning for the future, and shunning or being shunned if they leave or somebody they care about leaves, etc. Those practices SHOULD be banned.
It's not so much ban the religion but ban the practices that violate human rights and are deceptive since they are a religion that actively seeks out members instead of having them come to them.
