There are many in the Bassa camp who see this as part of a political movement (see the comment earlier about 'workers rising up') and the leadership of Bassa and Unite see an opportunity to be at the vanguard of that struggle to encourage political overthrow and even social revolution.
Also, the unquestioning minority only believe what is told to them by their 'trusted' leaders, and they believe it implicitly - everything else is part of a conspiracy to harm, undermine and break them, and is just based on lies, fear, ignorance and an inability to see the 'truth', which only they can recognise.
Clinically, it's called paranoia, and is exhibited by all cults as they engineer their own, inevitable demise.
