"these types of questions ...are used to try to caricature conservatives as extremists."
Yes, they are, in the same way asking a Klansman whether he'd hire a black man does. If a person holds extreme views, there's nothing wrong with asking questions that expose that (ditto for democrats).
Don't want to look like an ignorant extremist? Then stop answering in a way that panders to ignorant extremists on an uncontroversial scientific question. Stop pretending scientific questions are theological questions. Stop promoting scientific ignorance.
If you answer like an ignorant fool, you can't complain about being painted as an ignorant fool.
