As I understand it, in a stand-up, one is supposed to say what one did yesterday (I don't care), what one is going to do today (again, I don't care), and what road-blocks, if any, you have (and, unless your problems affect me doing my work, I still don't care).
So you're saying if a fellow team member is doing something in a way you think could be done better, you just stay silent? If a team member is planning to do something that you think isn't actually necessary because of something you're doing, you just stay silent? If a team member is struggling with a problem you have the skill set to help out with, you just stay silent?
It's true, for Agile to work, you need to have a team. The group you are a part of doesn't seem to fit the definition (or at least you don't).
