see, in principle, the question is if this works or not. it's an informal means of social control, and i'm in principle in favour of that.

perhaps i should clarify some of the remarks i made about fat shaming. i would certainly not recommend randomly attacking fat people walking by on the street for no reason; if my comments were misinterpreted to suggest i am proposing that we all go out and yell "fatass!" at every behemoth that comes across our path, i do apologize, as that was not my intent. rather, i would advocate that fat shaming be done in more intimate settings, by loved ones and health professionals, that have the person's best interests in mind. further, something that utilizes a little bit of wit is probably helpful; you don't want to depress this person too much, as that will just lead to more eating.

i think there's a different psychology to mask wearing, though. it's sort of a reversal of the situation, as it's usually going to be healthy people that don't want to wear the masks, and people more likely to catch it that want to enforce mask wearing. as a non mask-wearer, i can tell you that i'm not particularly concerned about the opinions of people that want me to wear a mask, and i'm just as happy to avoid them; part of the calculus built into my decision to not wear a mask is that i'm reasonably distant from people to begin with, and reality at the moment is that i'm just not walking into many high risk situations.

but, in the hypothetical scenario where i was living with a high risk individual and refused to wear a mask (in fact, if i was living with a high risk individual, i would without question be considerate enough to take all relevant precautions), due to some temporary deficit in thought, i would be likely to respond to an emotional plea that laces into me for putting that person at risk.

as with any means of informal social control, execution and context are key.
