I think we're on the same side as you have a similar sentiment to mine, but I don't think what you're describing necessarily intentional. People just act differently in densely populated areas. I walk differently when I'm in DC or Singapore or Ohio. One of the things is you get used to people being close in dense places in general. In fact, what you're describing might not even be interpreted as "aggressive" by the people you're walking close to in order to, I guess, communicate they're in the way. They may not even process it.
