I'm not sure how far I want to go down this rabbit hole, but why do we call such people 'conspiracy theorists'? Wouldn't 'wrong' suffice?
There is a huge difference between someone who just happens to be wrong about something and someone who is so far down conspiracy theory rabbit holes that nothing anyone tells them will make them see reality.
Remember many of these people believe things like 5G masts give you COVID etc (and a subgroup of that will be guilty of the terrorist attacks we have seen on critical national infrastructure). We are not talking about reasonable people who just happen to disagree with government policy.
I think that's a tough one to call. Obviously people need to be able to perform their important jobs, and any such video published should take great care to blur out faces etc., but equally I think we should have the right to know and/or investigate what is going on in hospitals too, when that is the reason being given for all the unprecedented laws and restrictions currently in place. And to be blunt, we can't rely on the corporate media to give us an accurate picture anymore, so to some degree we have to be prepared to take such matters into our own hands.
Again to clarify - these are not people who are genuinely want to report as a journalist on the goings on hospitals like you seem to be framing them as.
They are conspiracy theories who are trying to further their own agenda without a care in the world for anything else. No care about the staff, no care about the wellbeing of patients or what would actually give the patient the best medical outcome, no care about the fact that you know, they could actually be bringing COVID into the ward, no care about blurring faces / hiding identities etc etc.
It strikes me as somewhat similar to bloody Tommy Robinson and his elk who were attending court cases under the guise of "journalism" but were actually there just to cause trouble and rile up their supporters. No difference here.
In terms of these videos that these people shoot, from the cases I have watched / read about, they are very deliberately misleading. Filming in areas that are closed at that time (in one case it was a bereavement suite that closes after 4pm), filming in areas closed to the public (in one case they specifically pass clear signs saying "do not enter"), filming in entrances that have been temporarily turned into exit only areas (but still claiming it is an entrance and then asking where are the people) or filming in corridors which are usually quiet anyway as for the most part people are in beds on wards.
These people end up riling up supporters with their lies / misleading stories and then you end up with large groups of yobs outside hospitals abusing staff (like what happened in London on new years eve).
There's also been several where the person filming is shown arguing with doctors and medical staff when they have no involvement with the patient in the first place - how does that help at all? Especially when they make false arguments like the idea that COVID can be treated with vitamins, or that giving patients oxygen will kill them.
Maybe. It seems an unhelpful term to me, I'd prefer a simple 'wrong'. Dismissing people with a label tends not to change minds and may even attract others to agree.
To be blunt - these people and their "beliefs" deserve to be dismissed.
