if i were supposed to comment on the actual thing asked here that is Should the novels which force the readers to think the unthinkable be banned? than i would say a big NO..!!
'cause this is what you call fiction if people like reading fiction like to stay in fantasy world it's all their wish we can not ban it you must be knowing about DAN BROWN he writes all fiction books still his books have always been a best-seller that means people like it so no need of banning these books..
