I don't think it's as simple as everyone who follows rules doing so because they are rationally and unselfishly following the science while those who don't are selfishly following their own wants.
Of course not everyone. But I could say exactly the same thing about the people banging on about Milgram and Hitler Youth because they think it makes a better case than the truth, which is that they hate the restrictions (we all do) and don't want to bother any more. Which I can respect more than a ham fisted attempt to make themselves out to be noble critical thinkers defying evil authority.
I think people use extreme examples like the Milgram experiment partly as a reaction to the minimisation of the effect of lockdown which you see from some quarters (and I'm not accusing you of this).
You have a much more charitable view than I have of the motivation. I don't think many people are unaware of how shit and devastating lockdown has been, on account of the fact we have all been living under it, more or less, for over a year. My mental health suffered like everyone else's, but now we are on the home straight, I can handle a couple more weeks and if it turns out I didn't need to, well, it's a red light on a still road at 3am.
Even if the motivation for these bad comparisons is to try to express how awful it has been for those who suffered particularly badly, that doesn't stop it from being an absolutely terrible argument that doesn't help the case at all. Actively hurting another person, potentially to the point of death, because a man in a white coat says it's ok is about 10000 miles away from adhering to social restrictions because of a pandemic, the evidence of which we see all around us, not least from front line doctors and nurses. It's not the same as joining a fascist youth movement either; lockdown kept us apart rather than encouraging us to join movements!
As much as anything else, I dislike the deflection of what Milgram/Hitler Youth SHOULD be teaching us. They're not rent-a-rhetorics for everything one doesn't like. I could just as easily say that by breaking the law, people are causing harm like the average Milgram subject. I'm not, but as far as daft rhetoric goes, it works both ways.
At the very least, even if others are harmed more from lockdown than Covid, those of us who are choosing to keep the rules aren't causing that harm to them just by waiting for official restrictions to lift. We're just not staying overnight yet. We're really not hurting anyone. We're not taking it upon ourselves to strong arm anyone else.
There seems to be an assumption/implication among some people that adhering to the rules means lying in wait to grass up anyone you suspect of a minor infraction. It doesn't.
Once more, I'm sympathetic to all the arguments people have made. I'm not curtain twitching, I'm not reporting, I'm not cats bum mouthing. But I can't accept direct comparisons to Milgram and Naziism.
