So this isn’t just pregnancy related but I’m looking for opinions

Let me start by saying I have nothing against smokers. We can all agree it’s obviously not good for you but everyone is entitled to their own decisions. My husband is a smoker but he goes outside to smoke and never smokes in the car with our child or I present (he never smokes in my car period but when we take his vehicle he doesn’t smoke with us around). I used to smoke before getting pregnant with my first but I quit and didn’t pick it back up but anyways this is my story:

I’m 35 weeks pregnant and I took my 3yo to the park the other evening, I was pushing him on the swings when a father came along with his daughter who was maybe 2 at most, and was smoking his cigarette right next to me and my son. I tried to get my son to put his attention on the slides so we could get away from this man smoking, but of course my child was having too much fun where we were. So I tried to step sort of to the side to avoid the smoke which he kept blowing my direction 🙄 then he went to the front of the swings and blew smoke DIRECTLY in his daughters face. Like im not exaggerating at all like got down to her level in the swing and INTENTIONALLY blew in her face, she started crying and then he laughed, I was livid. So at that point I just said “Hey could you quit smoking so close to us, I’m pregnant and my son has asthma” (My son really really does) and this man got 2 feet away from my face started yelling at me while still smoking and blowing smoke telling me that this is America and he can do whatever he damn well pleases. At this point I got my son and we left, I grabbed his plate numbers and called the non-emergency just to let them know about the situation with his daughter.

But was I wrong for asking him to stop smoking? I feel like at a children’s playground next to a pregnant woman it was inappropriate for him to be smoking but I guess is that just the risk I take taking my kid outside these days? I know that we get exposed to third hand smoke from my husbands clothes and that it’s not like at no point in my child’s life will he be exposed to cigarette smoke, but that close? I just didn’t know if I was over reacting or if y’all would of handled things differently.
