The elephant in the room is dead. If we recognized it we would have to admit that it smells very bad as well as taking up nearly all the space. It only recently died even though it has been sick for several decades. And to admit that Trump killed it is still beyond the pale. So, as you say, there are too many groups and individuals that will not allow even the existence of the elephant to be mentioned even if it is dead and becoming more deadly by the day.
This analogy is unfortunately apt but that doesn’t do us any good at all.
