I'm fine with sanctimonious whiners with whom I disagree - be they Corbynites or Scottish Nationalists - but then they're not doing any (direct) harm to my health. (They'd ruin my health in a different way...) Second hand smoke - and the stench that generally accompanies smokers - is different.

I don't smoke - never have - and find it disgusting to have to walk down the road behind someone who is, or get in the lift with someone who stinks of the stuff. I'm fine with you doing it in private, but not in a public place.

Smoking is almost as bad as putting your feet on a bulkhead....
