Have a look at this comment which I have taken from an article on the Guardian website. At first sight it seems plausible, philosophically sensible even, but it is based on a completely false assumption.
" It's a bit like how I felt about homophobia for a couple of decades: astonishment that such a mindset existed. The fact that a thing exists means - it exists. Full stop. As part of the human condition. So how can anyone be 'against' something that is part of the range of human behaviour? It's a bit like saying someone accepts the presence of tulips and roses but not geraniums. Geraniums 'aren't right'. So we'll make a law against geraniums.
The 'is-ness' of a thing creates its own authenticity. No further justification is needed."
The assumption is that we live in a materialistic world with no higher truth behind it and no absolute reality. But what about murder? That exists. What about all the flaws of this world, what about human vice and error? They all exist. Does that justify them? Of course not. No one would claim such a nonsensical thing but this person seems to think that the mere existence of a thing justifies it completely. Note that word, completely. It is not just something to be understood but something to be fully accepted and given equal authenticity, to use his word, with everything else that exists.
If you don't understand the spiritual background to the world then you understand nothing about it at all. If you think that truth just means what is or happens to be then you have no conception of truth. There is an objective reality 'out there' which, by and large, human beings have always acknowledged with varying degrees of insight. Not now. Now we do not just ignore it. We actively reject it.
The single most destructive thing in the world today is metaphysical ignorance. It is this which is driving the ship of humanity onto the rocks of wreckage with the difference that in this case many of the sailors on board are actively steering the ship to disaster. A few shout out in warning but they are not heard. The good news is that the lifeboats are still available and will take anyone to safety if they just hop in.
I believe that the truth is in all of us and it requires an effort of will to block it out*. This means that the rejection of truth and attempt to establish ideas and modes of being that are in conflict with it is a moral issue. This is clearly more the case where there is active participation in falsehood but even those who passively accept the new status quo as it is established cannot be held entirely innocent. They are complicit in evil to some degree. God has not left us without witness to his reality, externally or internally. Those who deny him will be held to account.
God allows us to think or do whatever we want but if what we think or do is contrary to how life is we will suffer the consequences. We can eat rotten food if we like but we will get sick.
