Dog poo doesn't affect the health of other people.
There is no second hand alcoholism
And yes, when people drive like assholes like prepare to do a dangerous overtake, I'll move my car in a way so they know they can't try it. And I wont block speeding cars. I have called police a few times on cars going dangerously over the limit though
Also, other dog owners are pissed off when people don't clean up the poo.
Smokers have normalized leaving their trash on the ground and harming the health of others. And they don't care when other smokers do it. If smokers aren't going to protect non smokers, laws need to be used to do it for them.
