If I explain how evolution theories fit snugly inside of creationist theories, can we all learn to love each other and get along?
The issue is that you are using theory twice in this sentence, but in the context mean completely different things.
The first theory uses the scientific theory definition: In science, a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.
While the second instance uses the layman definition (since creationist theory has not gone through the rigorous testing by independent bodies that evolutionary theory has gone through): a proposed explanation whose status is still conjectural and subject to experimentation, in contrast to well-established propositions that are regarded as reporting matters of actual fact.
It's like fitting a square peg in a circular hole.
Or it's like trying to connect the theory of gravity with the theory that my nephew thinks the puppets on Yo Gabba Gabba really exist.
