Nobody’s perfect. But I do try to remain cordial with those I disagree with so long as they show me the same respect. But if they start calling Creation/ID scientists flat earthers, or Luddites, or cretins, etc, then they will probably find that they bit off a little more than they originally anticipated.
As for your question, the Bible is very clear, there is a very real battle (no matter how imperfect our understanding of it) going on between good and evil. And the Bible is very clear that God-denying evo-atheists are on the side of evil...and the Bible is just as harsh towards their contingent of fellow travelers who should know better, but instead persecute those who bear witness to the truth. If you want to call that extremist, then your argument is with Holy Scripture, not me.
Yes, but not everyone who disagrees with other people's 'interpretation' of Bible Verse that the Earth is 6000 years old, is a God-denying evo-atheist.
