To add some of my thoughts:
You may be a student, but you are in the USA - therefore a consumer (who pays tuition and invests time) and an American of independent thought - so act the part.
Be aware Martial Arts divorces and organizational schisms happen all the time.
When I was a fourteen-year old dojo rat in my first style it unnerved me to watch my first MA schism of senior students (my teachers) breaking away from their “karate master” – but now decades later it’s often par for the course to happen - over any extended period of time.
I would recommend these steps (for all in this situation):
1) If you continue to train at this dojo because it meets your immediate needs - in a private one-on-one you need ask the instructor about it (diplomatically). The manner of his answer is just as important as his words.
2) Is the instructor now a member of a break away federation from the previous organization or is he completely independent? Depending on that answer may have major impact of your long-term sword study prospects.
3) Or… ignore it all (politics) and just train for now and absorb as much as you can for your first year or two. But do independent reading/web research, maybe attend “outside seminars” to compare core techniques as your knowledge base begins its development.
4) If the issue really still bothers you, leave.
BTW, it is the multiple “hamon” events in your background detail that kind of bother me.
Like after getting your third divorce, maybe marriage isn’t the proper life choice for you.

Well, but you can't expect to wield supreme executive power just 'cause some watery tart threw a sword at you! I mean, if I went 'round saying I was an emperor just because some moistened bint had lobbed a scimitar at me, they'd put me away!
