I think you are giving the VHSL way more credit
Let me explain it to you. The VHSL is not suit averse but, they are not stupid. You trotted out the LCA situation seemingly without understanding the nature of the suit. First, under the Liberty umbrella, LCA had plentiful financial resources to contest a suit if it went to trial, likely far more than most, if not any and all, disgruntled Northern Virginia parents. Second, to further demonstrate their commitment LCA engaged Winston & Strawn LLP an international law firm headquarted in Chicago with substantial litigation resources at their disposal. Finally, LCA was fighting for a long term business objective.
I will ask you again, do you really see a disgruntled parent mounting a serious and substantial lawsuit and, if so, what is their objective/goal for relief? I have given the VHSL credit for recognizing the nature of threats and their best options to defend against those threats. Perhaps you can explain what you believe the VHSL has to be scared of in a suit surrounding this situation? You made a good call on the ban, not so much on the assessment of the VHSL legal peril, at least so far.
