A couple general pieces of advice:
- even if you are "blacklisted for life" by one journal, it's only one journal and many many many journals include book review sections
- book review editor positions are not glamorous and thus change frequently
- yes, the name-calling was inappropriate, but this will occasionally happen (along with all other bad habits of "Reviewer #2")
- the only time that you can send out the same written work to multiple outlets is when you are submitting book proposals to Presses
- if the editor was upset, this may have been because they were considering your piece for publication, and that's good!
