Wow, so many things I want to say about this. First and foremost, I am so sorry to hear of your experience! You are correct - every acupuncturist is different just like any doctor, massage therapist, nutritionist, etc. I have had good and bad experiences with all. In fact, I know one or two crazy vegans I would rather avoid due to that funky energy thing.
I am a licensed acupuncturist (on hiatus) and when I was in practice I actually helped people by encouraging them to cut animal products out of their diets. In fact, I led several clients on the Arise & Shine and other cleanses (vegan, raw, macro). This is unheard of in Traditional Chinese Medicine. But I was not practicing in China hundreds of years ago. I was practicing in Southern California in the 21st century!
In chinese medicine, the practitioner must look at the whole person, the individual. The region and climate in which they live. He/she must consider not just the patient's physical constitution, but their emotional well-being as well as their spiritual and religious beliefs and lifestyle. ALL must be honored and worked with. In fact there are many chinese buddhist vegetarians and I doubt a practitioner in China would tell them to eat meat.
I became an acupuncturist becasue I had such great success as a patient and wanted to share that. I was healed of chronic low back pain, as well as chronic bronchitis and adult onset asthma. A big part of that was due to the macrobiotic diet my acupuncturist had me adopt at that time in my life - which launched a life-long commitment to a plant-based diet. But my acupuncturist also got me on my feet (after laying flat on my back for days with acute pain) by their skillful use of the needles as well.
There are many vegan acupuncturists who are wonderful healers and would never behave in the way you described this crazy woman! I also want to point out that there is also a new trend in this country (thank goodness) of community acupuncture where they charge on a sliding scale (and I know private acupuncturists who work in this way as well).
Also, a good healer would never start the conversation by telling the patient how sick they are ("your liver is so weak....you're anemic"). That is just terrible!
Again, so many more things I could say. I would be happy to share info about the wonderful acupuncturists I know in Southern California who promote a vegan diet and who don't overcharge and who are generally wonderful healers. They are out there!
