This question is quite unanswerable. Whether 2 systems are compatible can only be answered by the teachers of the 2 systems. But seldom does a teacher happen to know another system in depth. In the old days when the very original system has been taught, undiluted and unadulterated for centuries. Then another teacher may have sufficient knowledge on that system. But these days many system are recent inventions, or significantly altered, then outsiders would have no idea on what is going on.

This kind of response is unreasonable. No one can do that, unless it is a very light one. And it didn't mention the primary appropriate response - flight, other than fight back or accept it whatever.

Definitely not MDT related or as an entry point into MDT despite the proximity. You can argue it is not a dantian, as when the work is completed in the back, the Chi would shift to LDT for further processing.

Karma must not be related to justice. Otherwise who is to determine an event is justice or not, and what is the yard stick? The same event can be right and wrong depending on many things and the view can change after time lapses.

Even normally Taoist used so many terms to describe a single object or process, according to their functions in the whole picture or simply due to some unknown reasons. Dantian and Mystic Gate are the terms that have many variations. e.g. the Central School says "between the outer and the inner Dantians". When they do not explicitly say LDT, it doesn't mean it is not LDT. I would say most people only use 1 or 2. When you say the spine, that is a good question, the location of LDT is not having a consensus. But the depth of Dantian inside the body is also not always agreed upon. Some say it is on the surface, 1.3 Chinese inches inside, the middle of the abdomen, inside the spine, the whole general area etc. The "Back" refers to the spot on the back of the body, behind the MDT (in front or in the middle). As far as cultivation is concerned, re ZZ (in another thread) and location of Dantian is not a big issue. Your system determines these. You are not supposed to change these yourself, even if you are very knowledgeable. It is not like a buffet whereby you can choose any combination of food.

The western and the central school use outside Dantian or multiple Dantians. The Fukien School uses the back as the Dantian location. And in different stages, people use different Dantian/locations.

My understanding for Dantian is the place you select to cultivate. It is the "field" as per the meaning of the word. Where do you till your field and grow food? It is naturally the place with sunshine, water, rich soil. In human body, we would choose a single place with best potential like abundance of blood, oxygen, nerve cluster, endocrine glands and energies to be the "field". So it is the reason to coincide with the locations of Chakra. Different systems made the same choice. Yet there are schools that use Dantian as place to rest the mind only. In that case, it doesn't have to have relationship with the Charkra or the other Taoist favourable potential "fields". It could even be outside of the body.
