I'd invite more scientific investigation of the field.
There's been quite a lot already. There is no science behind the core tenants of chiropractic, nor is there any verifiable evidence to support their more wacky claims. The practices of chiropractors that actually work are already done by physical therapists and related specialists.
Reminds me of Tim Minchin's Storm when he says: You know what they call "alternative medicine" that's been proven to work? Medicine.
So I suppose if you're educated and experienced enough to find a chiropractor who is only going to practice a sensible therapeutic intervention on you, then you might get some reasonable medical care. But then you still have to wonder why they aren't already a DPT.
Why is it that people jump on chiropractors all the time but not on psychologists?
Well, I agree that there's probably a lot of crap in practicing psychology, and there's also a lot of argument and controversy. But generally psychology practices trend along with the evidence. Cognitive therapy does actually have some evidence to show efficacy in certain circumstances, for example.
