It depends. I am learning on here how to more clearly state exactly what I am looking for and not looking for in a particular post.

Like in some instances, I may ask for opinions and/or constructive criticism by asking "did I do something wrong here?" "was I in the wrong?" or "how could I have handled this better?" Those kinds of questions invite constructive criticism and promote self-learning and self-improvement. And what's amazing about PC is that many of us are in therapy working on self-improvement and self-learning.

In other cases, I simply want validation of my experience or feelings and have learned to state that that's all I am looking for, rather than advice or criticism.

If we leave it wide open, people are left unto themselves to guess what the poster is needing or wanting, and it may invite unwanted constructive criticisms.

I think what's good and helpful is if the OP states what they are seeking from the outset. That way it's very clear and then any types of unwanted responses can be limited.

HUGS!
