I think this is a manifestation of the general upchuck reaction among women to Judge L's ruling excluding the DV expert. It does not seem to be the product of someone who is exceptionally well informed, but it seems to be an authentic and widely shared sentiment in the community.
Also, I think it's important to understand that the Colorado judiciary has taken a media beating over the past year for lack of integrity and transparency (e.g.
Auditor's report finds possible illegal activity among ex-Colorado Judicial Branch Employees and related articles), and to me it is completely understandable that a Colorado citizen might think Justice Boatright made insufficient inquiry into Judge L's credentials and potential conflicts before appointing him.
If the petition demonstrates concern among the community and stimulates more participation in the public dialog and especially more media comment from experts on DV, I think it will have served a beneficial purpose. It it won't hurt to have greater public scrutiny of judges either, including but not limited to Judge L.
