You haven't mentioned that they:

a) are aware that their smoke isn't dispersed enough by the breeze / open space to be unnoticeable.

b) know there is someone close enough who isn't like them and other smokers, and is really bothered by the smoke.

They do, however, go smoke on their balconies since they were made aware smoking inside is bad for their roommates/family.

So, many of them are more likely than not reasonable people. They _could be_. While you _proved_ that you aren't, by not communicating it (or at least not mentioning it as if it isn't the most important reason why they are "awful people"), just judging them and holding a grudge.

In this very comment you again showed that you don't care enough to understand others who you might disagree with, because I am just rephrasing what I already wrote, since you replied like I didn't.

No, in my experience they smoke on the balcony because it is banned inside and will get them evicted.
