    Start with Praxeology (the methodology of Austrian economics).

"Start with a fringe ideology that explicitly rejects empirical evidence" is not exactly a good start.

    The simple axiom that all preferences are subjective instantly eliminates a lot of the foundation of micro (and macro) economics as it is typically taught today.

No? If anything, econ 101 classes are basically Austrian economics classes due to how many idealized simplifying assumptions are made. And subjective preference curves are the entire basis of the supply/demand graphs that econ 101 students are bombarded with.
