I have said that I don't judge smokers. I have said that they should be free to smoke in their own homes or their own property. I wouldn't have a problem if they smoked in public, if there was a way for me to avoid breathing it. The problem is that smoke travels. It doesn't just stay around the smoker, it fills an entire area and it lingers.
I do believe that many, but not all, of people who smoke today are bitter about their choice. When they are asked not to smoke, or are questioned about their choice, they retaliate. That has happened in this thread. I knew it would happen, because it happens in every thread that discusses the subject.
