Well then we should ban farting too. And body odor. And too much cologne/perfume. Petition your government. I'm sure you'll find enough fellow nanny-staters to stand with your cause and pass even more laws, 'cause we don't have enough of those.
No one’s farting, bo, perfume lingers for hours or days, nor can you smell it from across the room. Those other smells don’t permeate someone else’s clothing either. There’s no comparison.
What a stupid thing to say. Second-hand smoke is hazardous to your health. As far as I know, farts are not.
