better than "heretic"
history makes perfect sense when it comes to understanding culture and even biology- with regards to evolution, we have fossil records that support our general views, even if there might be missing links and lost information. we have plenty of religious fossils also, and they might lead back to a common ancestor or several, just as we didn't come from apes but share a thing that goes farther back.
regardless, an understanding of the past leads to greater context for, and better understanding of the present. god makes a little more sense then, but christians don't
actually there is plenty of room for them, but like with all people in history- the planet, as well as god and philosophy, will just have to be shared.
this is something that politicians obviously have a job to misunderstand, or ignore. but i'm still sorry that i ruined your joke - not too much, but just enough
