This comes down to a difference in definition of freedom, based on what you hear, vs what I'm saying. It's a common problem across all people. When people don't know the definition someone's using, we'll hear the definition we think of and react, when that wasn't the definition that they meant.

In the Bible, those who sin are slaves to sin.

Those who "do whatever they want that's right in their own eyes" are the most enslaved people.

Contrastingly, those who the Son sets free is free indeed! and the ones who are freed by Christ also imitate Christ and do not do the deeds of darkness. It doesn't mean Christians don't sin, we struggle and sin often. It means, we no longer have a mind that is beholden to darkness and nothing else, we're freed from the slavery of only obeying our flesh. We are now free to have a mind that puts Christ, puts God in the proper place of worship in our minds and heart, we're free to choose to hold our thoughts captive to Christ...You become a slave to Christ, but everyone's a slave, either to their flesh (which is ultimately a slave to Satan) or a slave to Christ. Only in Christ is that slavery a positive thing and is more like freedom.

That's true freedom.

Now even among atheists, when the society was more Christian minded, it helped their mind even if they weren't aware of it. There's a reason why even atheists could write good art in the 20th century....because their mind was being influenced by Christian thought subconsciously in ways they weren' even aware of it, even if they were anti-Christian themselves.

So when I say a "free mind" , I'm not talking about the libertarian "everything consensual is permitable dude...." freedom.

I'm talking about a mind that isn't subject to being given over to the Romans 1 depravity that minds get given over to, that in modern day West, we are seeing in huge swaths of the West.

Having a mind that isn't utterly given over to depraved mind is the ultimate freedom in terms of having a mind and being able to create art that is worthwhile.

With a mind that is given over, the best you can produce is ugliness, tearing down what's beautiful....etc.
