Why are the left it right wing not demanding the bible is banned?

Why are the left of right wing not demanding the bible being banned? Normally they love to jump up and down in excitement demanding something is banned if it has a connection directly or indirectly with a crime. Such as porn or computer games or a film or tv show or a book or even music. So considering this lady seems to have done this crime because presumably she has mental health problems and the bible and religion seems to have been a huge factor presumably the left or right wing will be demanding the bible banned. On a side note I often wonder if I was to write the bible today would I be in prison as it is full of people having sex and in ways sometimes that are clearly not legal. Indeed one wonders if some parts are even legal these days.
