Health- You did not say that you did not read the article in your first post. You only stated that later after everyone was bashing you. This is how Lashon Hara starts. You tried sspreading Laz about Mishpacha based purely on secondhand information. Please do not do this in the future.
They are making an Asifa against internet because that is becoming a major destruction to Klal Yisrael in both terms of gashmiyus and ruchniyus. Many people still do not believe it is that bad to have internet and are not convinced that it will be damaging to them. It could damage anyone, even the guy who learns the most and has the best middos.
The other things you mentioned are definitely a problem, but are not as bad. Most people understand that drinking and smoking are bad. The majority of Jews have internet, and I believe only a minority smoke or have drinking problems. Anyway, maybe they will do something major like an Asifa about the other problems if they see that this will work. You cannot work on everything at once. One thing at a time. If they would’ve picked alcoholism then you would have got upset that they weren’t doing smoking or the internet. Just understand that the Gedolim are doing their best to combat this menuvaldika American society as best as they can.
