Kevin, the real issue is bullying. One would think the NEA already has their plate full with other problems...academic excellence, or the lack of it, for starters.
Teaching is the very last thing the NEA cares about. Way up there, on their list of priorities, is political power.
Want to stop the NEA? Help get the RATS out of Washington. (I address this especially to those conservatives here who say there is "no difference between Republicans and RATS".)
RATS and NEA... go together like a horse and carriage.
