Maybe you're just hanging out with the wrong crowd, or maybe you're a little too egoistical. Maybe a little of both.
Actually I rarely encounter rude people as my friends are all on a nice wavelength, I occasionally encouter rude people at random like on a train (or on forums). As I'm trying to follow the path of emptiness I'd hope that my ego matters less to me that perhaps other people's does to them (hehe, I'm not hoping from an egotistical point of view either, so don't go there, just a self-improvement point of view) - but it is what it is I'm not gonna get hung up about it.
