They way people attack one another here suggests that it is definitely NOT an OPEN forum where one can express oneself freely and that unless you tow a certain line whether openly suggested or implied you are going to get ostracized, torn apart and insulted ! [As many were when exiting / fading the JW .ORG etc ]
This is probably the least robust forum I've ever been on, but it's still not a KH, if you make a statement expect to be asked to back it up with some evidence or at least some sound reasonng. That seems very hard for some people though - especially those who have spent a lifetme not having their statements questioned by the sheep.
