The question of personal hygiene is a total red herring to this discussion.
Yes, those who don't wash, or overdose with perfume etc... can be offensive, but someone who indulges in a recreational habit, no matter how addictive, that is undeniably unhealthy to the extent of being lethal to themselves and those forced to share their habit, does so from choice.
Nobody is asking that they be "banned", just that they practice their habit where it doesn't effect those of us who don't wish to share it - that doesn't seem particularly unreasonable or intolerant to me.
I'm a bronchitic who loves folk music; it seems outrageously unfair that I should be asked to stay away from my music because somebody who has had the bad luck and bad judgement to get hooked on a lethal habit and can't be bothered to make the effort to step outside whenever they feel the urge to shoot up.
Am I missing something here?
