Understanding logic — and logical fallacies — helps out here. I recommend Biblical Logic inTheory and Practice, by Joel McDurmon.

From the Lamb’s Reign cover blurb — bolding my favourite bit:
In the so-called marketplace of ideas, Christians face countless attacks on and challenges to their faith, many of which engage in subversive rhetoric and logic in order to undermine the whole counsel of God. Whether coming from skeptics, atheist, leftists, cults, or even other Christians, poor logic and dubious reasoning deserve exposure and correction. In his new book, Biblical Logic, Joel McDurmon returns to God’s Word to recover logic and critical thinking from the hands of the enemy, and to expose the fallacies of unbelief and unbiblical ideas. But is the Bible really the place to turn for logic? Is not logic the domain of scholars and philosophers? The British philosopher John Locke long ago answered this common misconception: God has not been so sparing to men to make them barely two-legged creatures, and left it to Aristotle to make them rational. In other words, logic existed and people reasoned and used the critical faculties of their minds long before any philosopher came along to teach about it. God created logic and reasoning as He created man, and He created it for man, and therefore we should find it reasonable that God’s Word has something to say – if not a lot to say – about logic, rationality, and good judgment. Christ has made us priests and kings (Rev. 1:6). He has determined that His saints shall judge the world, and even judge angels (1 Cor. 6:23), and He has thoroughly equipped us to perform these tasks. God’s Word sets the standard of reasoning and law by which we shall judge, and the Bible teaches us this standard – a standard we must follow and to which we ourselves must give account. This new book, Biblical Logic, returns to Gods word to find that standard, and to recover the God-given directives for faithful logic and critical thinking. By this standard, and by this example, Gods saints – you – can indeed discern and judge the world as God has commanded.
Good , godly, self-governing judges must understand and use sound logic, created by God and integral to His Law-Order.
Logical fallacies and moral failures like straw-men arguments, appeals to authority, groupthink, univocal educational and media establishments, stacked evidence, and/or flat-out lying (by omission, commission, and half-truths) are quite useless here.
But they ARE useful to certain Man-centred political movements, where temporal power is the focus.
Not eternal truth.
