It’s worth making a distinction between something inherently damaging like alcohol, and something that most people can engage with in moderation and face no issues, like sugar or porn.
This I agree with, but your “in moderation” should be emphasized. Too much sugar - well, it’s obvious. Too much porn - one can really, honestly, seriously, I’m not joking, got serious hormonal and even mental problems.
Yeah but not to the point of making a scandal about it. Porn faces more alarmism than it justifies, getting accused of being the downfall of society on a regular basis. There are merits in pointing out some people can have problems with it, but most can manage themselves just fine.
Even when it comes to sugar, the “obviousness” of the matter for many becomes a matter of judging people for their looks, or a moral outrage against gluttony and laziness, rather than any real concerns about people’s health and well-being. Say, you don’t really see people being judged for their lack of sleep in the way they are judged for being fat, even though that is also pretty unhealthy.
It’s not about looks, it’s exactly about health.
You do see people being judged for the behavior resulting from lack of sleep, wrong food, some addictive habits and so on.
