Hi! I lived in Seattle, in SF and I’ve been to Portland many times. And I’ve seen the behavior I’ve described in all of the locations I’ve mentioned. Personally. With my own eyes and ears. More than once in each place! Strange, that.
So I don’t know…right back at you with the stereotyping thing? Because what you’re doing is taking your own limited experiences, overgeneralizing those and throwing shade at people who say things you disagree with.
(Also, by the way: the “please stereotype less” response is practically a whole delicious stereotype in itself. And here you are using it! The way non-passive-aggressive people say what you’re trying to say is: “I think you’re wrong, because I’ve never seen that.” This approach has the distinct rhetorical advantage of being honest, clear and direct, but of course, lacks that emotional punch of trying to belittle your inquisitor with a subtle insult.)
