Because this is a forum and nothing I say matters.

The problem of course is the question - What gives anyone a right to do anything? What gives you the right to police the comments? What gives me the right to question your questioning? Meta-discussions always get sidetracked..

What makes you think it is not?

Because it's rude and antagonistic and it compels a lot of people to post to defend themselves. It's classic trolling.

It's not constructive, who cares what you think about CLI users? The fact I'm being downvoted says a lot about the state of this forum.

Your comment was also trolling: I would have avoided the leading question and just commented on the probable negative interpretation the some CLI users might make of the comment.
