I can't see the parent of this comment (defederated or blocked, idk), but it's possible SmarterEveryDay believes in creationism as I believe he's Christian. That said, I watch his channel religiously (har har) and as far as I can remember he hasn't spread any creationist propaganda.

The worst thing he's done is make videos supporting the US Coast Guard. They're still interesting and informative, but it's still military propaganda in some sense. It's fairly tame though.

There are probably other edutainment creators to worry about more than him.

The end of ever video includes the name of a bible verse, Destin is not exactly hiding the fact that he's christian lol
