I like this, and it very strongly hints at my answer towards your questions, Carlos. When do we know where to draw the line:
Consent.
In order for antagonism (or rudeness) to be effective, the person being antagonized must throughouly understand and be willing to participate in the process.
I assume, that anyone serious about studying here is open to this methodology, though I would most certainly stop if explicitly asked (the "degree" of rudeness - i.e. invasiveness - not the process of questioning itself).
There are always things that will bother us. It is up to us to decide whether we will face the pain that comes from conflict - and claim the prize of self-ownership, or escape into a safe space where we can dull the pain with the applause of well-meaning enablers.
