Looking at the entire paragraph, I am reading the last sentence to mean:
Texts should be interpreted as parables except if strong evidence is required.
The final sentence is a description of the fundamentalist position (world created 6000 years ago etc):
Texts that seem to describe historical events should be interpreted as allegory only if strong evidence requires it.
This means "Texts that seem to describe historical events should not be interpreted as allegory, unless there is strong evidence that the texts are intended to be allegory".
Your suggestion:
"Texts that seem to describe historical events should be interpreted as parables except if strong evidence requires it" is the opposite point of view.
