This circular reasoning is quite amusing.
Posters have explained in detail why banning the parents from the site and refusing to communicate with them other than by email was a breach of various laws and statutes.
The police have confirmed that the parents committed no crime and therefore this behaviour from the school seems to be totally unreasonable and disproportionate as well as illegal.
You are then trying to argue that the fact that the school took this unreasonable, disproportionate and illegal action constitutes evidence that it was in fact reasonable and proportionate to do so (ignoring the reasons that have been explained several times now why this was also illegal, but we’ll leave that aside for a moment) because the school wouldn’t have done so unless it was reasonable and proportionate to do so.
Do you not see any issue at all with your logic here? 🤦🏻♀️😆
If such reasoning had any logical validity then by definition any action a school might decide to take would always be reasonable and proportionate because a school would never do something for no reason and a school decided to do it so it must be reasonable and proportionate by definition, in @Hercisback1 world.
The glaring flaw in your reasoning, lit up in bright neon lights, is the underlying and unquestioned assumption you appear to hold that schools always behave in a reasonable and proportionate manner.
It is self-evident that one cannot, while holding such an assumption (which copious evidence in many cases, not just this one, disproves and refutes), reason in any logical or rational way to determine whether a school has or has not behaved reasonably in a particular situation. Hence your seemingly unshakeable belief that whatever a school has done by definition must be justified and correct.
The lack of rationality is quite mind-boggling.
