It seems to have been a combination of both.
Was the strange man intent on harming the women?
We may never know.
Was the anger the man displayed towards the women uunjustified when you take into consideration the fact the smoking while pregnant contributes to birth defects, low birth rate, down syndrome, etc...
This is a loaded question on your part. The anger of the man toward this woman was without a doubt misdirected.
As to your assertions about smoking and its contribution various birth defects - the jury remains out on all of that. I've heard some crazy assertions of what maternal tobacco smoking does to the unborn child, but Down's Syndrome is NOT one of them.
Who will pick up the tab when this women delivers an unhealthy baby because she exercised her right to smoke, therby poisoning and injuring her unborn baby?
How do you know this child will be unhealthy? I smoked through my pregnancy and my 4 year old is as healthy as a race horse. And she is far smarter than some of her contemporaries. Please do not make generalizations based upon personal prejudices.
I have no problems with people smoking if that's what they want to do, but when it hurts somebody else, there has to be a trade off.
The only person hurt here was the pregnant woman who happens to be a smoker.
It's one thing to berate someone and qujite another to pull out a handgun and start busting caps.
What right does some stranger have to berate another adult engaged in a perfectly legal activity?
