That is not true. If a user asks a question about the rules or the validity of a post/flagging, it's fine to discuss.

You don't like the fact that I'm criticizing this thread, which is fine, but stop trying to cherry-pick silly reasons to discredit what I'm saying. It's having the opposite effect of what you intended anyways.

Yes it is.

That is just your opinion. Rules are clear on this:

Please don't submit comments complaining that a submission is inappropriate for the site.

As you can see, no additional caveats are listed. Therefore you, by responding to a comment which was about incorrect flagging, complained about inappropriate submissions, directly violated the rules.

Your last paragraph is basically just ad-hominem.

I'm ending this "discussion" here and will not be reading your inevitable further comments.
