Nobody is perfect. Smoking is bad but you can’t define the whole person by one traithabit. You can’t judge someone’s yiras shomaim by a single trait or habit.
And what does it mean “considered otd ” should they be despised as otd? Well are you supposed to hate otd people?
Or does it mean they are at risk of abandoning the torah? That doesn’t make sense.
Or does it mean the community shouldn’t condone smoking and smokers? The western world is going in that direction. I don’t like it myself. I think individuality is more important than health risks. But I can live with that.
Many frum people think they know the single formula to being a good jew (“?? ????? ??????? ?? ???”) some say it’s not having a computer and internet. Others say it’s never having a job and staying in kolel all your life. Now I heard about not smoking being the most important. The fact is the torah is bigger than any of that.
