The Planet Earth knows nothing of Creation
Sounds like he were doing his job and the students a service.
Look - I (personally) think young Earth creationism is total BS. But - by bringing up an alternate point of view he were doing something that far more teachers should: teaching the students to examine the evidence and THINK. Not just vomit up whatever textbook the professor happened to write last summer.
There's his problem right there. He was a lab tech. Going off and speaking at a conference (any conference, but a YEC conference is going to draw more attention) and holding himself out as a "Biologist at CSU-Northridge" was not a smart career move, to put it mildly.
If people want to say he was fired for his religious beliefs then fine. I'd say that if he was spreading young earth creationism in an academic setting then I'd say he was fired because he didn't know his field.
Having said that, I'm puzzled by these goings-on. Did he in fact find soft tissue in bones that should have been completely fossilized? That is, tissue that hadn't become fossilized? That's a crucial issue, but it seems to have become lost in the debate over his alleged religious beliefs. If true, it's an important scientific finding, with lots of implications for what we think we know about biology, chemistry, and a lot of other things.
Finally, I'm disturbed that researchers were digging up bones only to break them. Surely there are better ways of getting samples from their interiors than destroying the bones. Doesn't sound like good science to me.
