These people are completely blind. They are lost to humanity. They make up fantisies that ghey wish to be true, then convince each other they are true with no proof or logic or reason. They willfully live in a bubble of unreality they have created. Leave them to their fate.
"This is not the wisdom that comes down from above; it is earthly, animalistic, demonic. For wherever there are jealousy and contentiousness, there will also be disorder and every vile thing."
James 3:15,16
"They are in darkness mentally and alienated from the life that belongs to God, because of the ignorance that is in them, because of the insensitivity of their hearts. Having gone past all moral sense, they gave themselves over to brazen conduct to practice every sort of uncleanness with greediness"
Ephesians 4:18,19
