Yekke – +1, especially for your second and fourth points. I was going to respond (similarly) but wasn’t in the mood so I’m glad you did. You probably did a better job than I would have.
I definitely agree that “Yeshivish” can not be defined as being in Kollel. While there are several possible definitions (it can either refer to sociology, hashkafa or religious level), it is inaccurate and unfair to define it based on whether or not someone is in Kollel, imho.
