It depends on what the concerns are.
If the concerns are “DA GUVNA IZ GOINZ TO PUTZ US IN DA CAMPS.” Then yes, their concerns are invalid.
If the concerns are “a physical exam should always be necessary” or “the governor doesn’t have this specific power.” Fine. Have that argument.
There are numerous people in this thread who have explicitly or implicitly indicated the former rather than the later.
The later is a valid discussion to have, the former is just crazy.
It seems you do not understand the irony in your stated position, ergo those whose positions you deem “invalid” are necessarily “crazy”.
While I believe you have manifestly demonstrated a propensity to erroneously assign opinions and motivations to others, as well as repeatedly invoke any number of logical fallacies, I do not presume to assume your behavior falls within a DSM stipulated disorder.
I would encourage you to consider current events and their implications in an historical context. It is not an unfounded conspiracy theory to state the Nazis, communists and other tyrants - including currently within our own nation - have abused declarations of mental impairment to detain those in opposition to their dictates; often sending the “impaired” for “quarantine” in hastily constructed camps.
Though I am not saying that is Governor Lee’s intent, I cannot totally dismiss as “invalid” the concerns of those who see historical parallels, for to do so is to be ignorant of both history and the innate tendency of those with power to abuse said power unless otherwise constrained.
