This is the type of cultish behavior ...
But that is the problem, IT ISN"T !!
This is perfectly normal for mainstream conservative christian churches.
Trying to claim this is proof of them being a cult is a claim too far IMO. It just doesn't fly. if being successful in your argument requires classification of so many religions as cults then it probably won't be successful and may indicate your criteria are wrong.
Maybe it's that I'm arguing from the perspective of realism and pragmatism and you seem to be from an absolute 'right'.
I think all religions are cults and should be banned. But it's not going to happen any time soon and it's pointless to campaign for it - no one will listen.
Better to campaign for the low hanging fruit - the things they do wrong that can actually be proven
