Grilling: Outside
Fireplace: Vents Outside
Church: No Physical harm. Mental "harm" is questionable as even harm and nothing that's not sloughed off. Many people who grew up religious even on this forum sloughed it off when they were older.
In other words, your argument is not only ridiculous, its not even logical, so you just effectively slaughtered yourself as far as trying to make a point anyone would actually listen to.
I don't care about smokers, pot smokers, drinkers, and anyone else taking any myriad of substances in an attempt to escape the harshness that is the day to day. That should be a PERSONAL choice however and not involve anyone other non-consenting person, whether adult or child. But I'm also all for choice. Which is why I have no problem with restaurants or public buildings allowing smoking. People who don't like that can eat or shop elsewhere. However, in the situation of a minor in a household, that person has no such choice. And your point about second-hand smoke being blown out of proportion just shows how your "points" have no basis in reality. I was *never* bothered by cigarette smoke (though I hated the smell), but my brother, who had bad asthma as a young kid, would get thrown into an asthma attack if he wasn't watching where he was going and walked past someone smoking. Someone like him likely would have ended up dead or severely debilitated if he were forced to live in a household surrounded by smoking.
