No, wrong. Terrible stuff, Xunxian.
“By what right do you judge” - completely irrelevant. Also your comment earlier about how we shouldn’t get on a high horse about skin cancer, because there are several other much more potent killers out there - nonsensical.
The point is not that we are judging individuals harshly for doing things that we do ourselves in some generalized sense. The point is that we are pointing out things that are wrong, or stupid, or detrimental. If a murderer criticizes someone for drunk driving, is he wrong? Of course not - the criticism is perfectly correct. What is wrong is the idea that the murderer feels superior for not drunk driving himself. That would be stupid - but that completely misses the point.
I personally detest it when people put off criticism or advice based on that kind of argument. A murderer - and indeed everyone - should criticize drunk driving, because drunk driving is wrong and bad. Under no circumstances, and coming from no person, is this criticism wrong, hypocritical, or otherwise unwarranted. Whether or not you get to feel superior in making the criticism - well, that depends on the individual, and can indeed be wrong or hypocritical in some situations.
Same with criticizing people who damage themselves by sunbathing. In most cases, people who tan excessively are doing themselves a disservice by sacrificing their long-term best interests in favor of their immediate best-interests. There is nothing whatsoever wrong with criticizing this sort of behavior. We simply need to be sure that the behavior is actually deserving of criticism (which it is for most but surely not all sunbathers), and also that we don’t go about feeling superior because of this criticism, which would often be detrimental.
The idea that we should sunbathe now because it feels good, and live a life where we indulge ourselves immediately, is obviously stupid. By that logic we should max out our credit cards, because the consequences won’t come for months or years. We should cheat if we’re married, because the consequences won’t come until later. We should do heroin, because it feels great! Stupid, stupid, stupid.
This isn’t to say that we should live a life of bland asceticism. Obviously there’s a balance between indulgence and asceticism, and that balance is not some fluffy idea about what feels good, or something based on human rights, or anything like that. The balance is quite simply, what will cause my life to be the best overall? Ignoring pleasures won’t do it, and tanning, smoking, and drinking myself to death won’t do it either.
Smoking is stupid especially because people are completely aware of the consequences. The criticism that sun-bathers and tanners seem to have their own world of denial, where they are shocked when they get skin cancer, is also a completely valid criticism. Smoking is more retarded because it’s more lethal, more expensive, and the “cool” factor is more pathetic. But sun-bathing is still bad, because to obsess about your looks to such a predictable detriment of health sets a precedent that helps you become a shallow, self-absorbed person. And, as has been said, you don’t have the excuse of addiction.
I don’t get to tell anyone else what to do. I absolutely get to tell you when what you do is stupid. I do stupid stuff myself, occasionally (although honestly not nearly as much as some of you other posters). This doesn’t mean that my criticisms are hypocritical. My criticisms apply just as much to the stupid stuff I do as to the stupid stuff other people do. I don’t go about making criticisms to feel superior - I am critical because I think it’s pathetic when I use some excuse to allow myself to become a worse person, and I think it’s pathetic when others do it too.
