IRL, you see chiropractic practices all over the place. The average person sees them as a legitimate medical profession. You can even have one as your PCP, or get a DOT physical there. There are hospitals with entire chiropractic wings. It is a common topic of conversation to discuss your regular appointment with the chiropractor last week.

Yet if you bring up the field of chiropractic with your average 4channer or redditor, you are certain to get a disapproving lecture about how it is a mere pseudoscience, even dangerous, that has no merit in the field on medicine at large, and any benefits to the physical body or relief of pain issues dismissed as a mere overlap with the true medical discipline of physical therapy.

What gives?

That is the Wikipedian view of chiropractics, so most heavy Internet users will adopt that opinion without question. This seems to be a political issue, as the practice has been at odds with mainstream medicine since at least 1990, and this article indicates a much longer feud.

Alternative medicine and medical practices are characterized by their minimal effects on the body with correct dosage or technique, but dosed or performed incorrectly could lead to injury, especially among patients who are recovering from a severe accident or have conditions such as osteoarthritis. These risks deter medical officials and insurance companies [ (:^)_|\ ] from recognizing alternative practices. A chiropractor working in a hospital will be held to a higher standard by the hospital administration than a chiropractor working out of a strip mall, and so the concerns of malpractice upon recommendation are lessened.

It also does not help the reputation of chiropractics that many clinics are attached to, or are themselves, a one-stop shop for alternative medicines, be it crystals, essential oils, vitality tinctures, or the infamous treatments for Coof-19, of which Ivermectin has ascended to a cult status of a Panacea, the legendary cure for all ailments and a promoter of longevity. While these wares are mostly harmless, they do drain the wallets of patients who could otherwise use the money for more enriching activities, i.e. creative hobbies, working fewer hours, social recreation, or workshops at education centers. When these alternative treatments do not work, the shops will encourage customers/patients to consume more or a different variety of products. This parallels with the mainstream clinical practice of prescribing patients pills or injections at a very high price, which have little effect compared to lifestyle changes.

Two personal anecdotes:
1) My mother's chiropractic clinic offers its services as a subscription, and for a much lower per-visit price than a walk-in. This arrangement encouraged her to visit often, yet she went three months without a visit, only saying, "I should go to the chiropractor this week." Thus, $150 was lost for absolutely no services provided, and would have continued if she did not have a semi-annual financial crisis caused by impulse purchases. It is this manipulation by medical practitioners which concerns me most, as it is their business not to cure your ailments, but to sell you cures for your ailments.
2) My Vietnamese green grocer recently decorated their store with various Buddhist ornaments, but also erected an advertisement for the aforementioned vitality tincture, made of various medicinal herb and animal extracts. It purports effects such as alleviation of hypertension, lower back pain, high cholesterol, morning sickness, hay fever, a few other items, and, lastly, the effects of Agent Orange. While at the time I thought this final item was quite humorous, I now find it both sad and sinister than there is a target audience who seek remedies to twentieth century human atrocities yet are sold some mixture of industrial byproducts and dried oriental weeds, not that it is too far from the current synthesis of medications by pharmaceutical companies using petrochemicals.
