The counter argument is that the abortionists do not provide the honest counseling required for informed consent.
But if those who do provide adequately informed consent become more vulnerable to litigation (lawsuits based on previously discussed risks and benefits accompanied by a voluntary decision on the part of the one accepting the risks), then the argument will be made that the same applies to adequately informed consent in all "medical" practice.
The unintended consequence in this legislation carries with it the risk of windfall of malpractice jackpots not just in the case of abortionists but for all of medical practice.
