It can be true of anyone. But I’m specifically talking about mingling religion and science.
Take Nathaniel Jeanson for example. He’s written a book that covers a lot of subjects, biogeography, population genetics, systematics, etc. Was he genuinely interested in these fields? No. He wanted to write a book about his biblical beliefs and make those beliefs seem scientific so that’s why he delved into those subjects. When you have a religious agenda you are only going to be interested in the science as long as it serves that agenda. That’s the problem.
