EDIT: I have asked the moderators to close this question (by flagging it.)
We shouldn't ban a user because of his/her hair color. A meta post on this topic would be pointless because no one is banning users based on the color of their hair. If I want to discuss the practice of banning users for being blonde or redheaded, first I must prove that it is happening.
I have provided no evidence to prove that rules ARE being selectively applied. No one who has joined the discussion has shared any anecdotal evidence that it is happening. In my own recent question the some answer-like comments were deleted because of user flags. They were not removed through any sort of moderator bias.
A philosophical discussion about how to conduct yourself is only useful when it addresses areas of actual concern. It seems that this is not a helpful question, as the community does not seem concerned about this particular (non-)issue.
The original question follows.
After reading the post above, I feel like I have a pretty good handle on what comments are not. I'm not sure I agree with all of the points there, but judging by the votes, it seems like the community has some consensus about how comments should and should not be used.
The greatest area of debate hinges on whether brief answer type comments are OK. Some people feel that short "helpful" comments that aren't fully fleshed out answers are OK, but judging by the votes they seem to be in the minority.
The "When Shouldn't I Comment?" section of the Workplace help page for comments leaves very little to debate on the subject when it states:
"Comments are not recommended for any of the following.... Answering a question or providing an alternate solution to an existing answer; instead, post an actual answer (or edit to expand an existing one.)"
For the purpose of this discussion, let us then take as a given that "answer-like" comments are frowned upon when applied to the original question, and may be subject to deletion.
The question I would like to ask you all today is: should we apply the rules selectively to delete answer-like comments we don't like or disagree with?
