Does the verse 4:140 include scenes of fictional gods or is it refering to explicitly mocking or denying a Quranic verse?

So this ayah in Holy Quran (4:140) states, "He has already revealed to you in the Book that when you hear Allah’s revelations being denied or ridiculed, then do not sit in that company unless they engage in a different topic, or else you will be like them.1 Surely Allah will gather the hypocrites and disbelievers all together in Hell." Does this ayah include every instance of kufr/shirk including fantasy ones like a movie where there is a fictional god or a book about greek mythology? Or is it refering to explicitely denying or mocking a particular verse of Holy Quran? Also the ones has done it, has he commited a major sin or a minor sin?
