Actually you can win a prize for defending smokers, no matter what – whether it’s dangerous and Ossur from the Torah -you’ll still defend them.
Why if it’s Ossur they aren’t being thrown out -is a question you have to ask them. I’m not a RY and if I would be one – I’d be from those who throw out Bochrim for smoking from their Yeshivos.
And that is what makes us both LWMO. 🙂
It is a matter of priorities, and smoking is so low down, it is being treated as muttar.
