I did mean to imply otherwise. I was under the impression that criticism in the Unbounded category might have (possibly unintended) negative social content.
From About the Friendly category:
Discuss, think and learn with a friendlier atmosphere. Avoid tangential, meta, indirect, personal or harsh criticism.
This implies that the atmospheres of some other categories on the forum are less friendly and might contain harsh criticism.
I prefer a friendlier atmosphere. I think I would be okay with tangential, meta, or personal criticism. I think I would dislike a less friendly atmosphere and indirect or harsh criticism.
