But that kind of "take it or leave it" attitude (although perfectly reasonable) ends up making life even easier for those who don't want to engage with science.
You have a good point.
Your challenge is to get them to step forward and "engage with science".
A dismissive attitude will be alienating.
However, it is a difficult challenge, because so many creationists seem unwilling to play by the rules of science, let alone engage it. Most don't exact the requirement for some sort of physical evidence before believing in something in the first place.
If they believe in a God and creation without any physical supporting evidence, why shouldn't they believe in a conspiracy theory against them without any evidence?
You'll note that you haven't had any of them step up to the plate yet on this thread, but I'll have to check back later in case any do
