| A few millimetres, according to this Twitter post:

| The post is about a curious discovery on Mars.
|
| The commenter joined the conversation about that discovery

|
| There is no getting around the fundamental ignorance and
| offensiveness of that.
|
| My comment IS exactly about conversation not about Mars.
|
| It's about the curious but not at all uncommon phenomenon
| of joining a conversation for no other purpose but to tell
| everyone in it that you are not interested in it.
|
| My point is to point out that that is what they are doing
| when they do that, not merely adding their own perfectly
| valid opinion on a topic the same as anyone else's. It's
| uniquely invalid and offensive.
|
| It's walking down a hall, hearing a conversation behind one
| of the doors, stopping, entering the room, and announcing
| to everyone in that room "It's stupid to discuss this
| topic".
|
| Obviously, the ignoramus who does this doesn't realize that
| this is what they are doing. Obviously they think they are
| delivering a valuable observation and conclusion, or at
| least expressing their opinion which they are entitled to
| have and even to express.
|
| The problem is the context. They were not already in a
| conversation where something came up and their opinion was
| relevant. They were not specifically asked for their
| opinion like with a poll or an article that poses the
| question. They went out of their way to join a conversation
| in the first place for no other purpose than to say it's a
| pointless conversation.
|
| I am distilling their action to it's essense to expose just
| what they are actually doing, and lay bare the lack of any
| valid motivation for an action like that.
|
| You are supposed to see this, and understandably try to
| find a hole in it to save face, but then eventually when
| there turns out to be no way to avoid the essential facts
| after unpacking, realize that's what you're doing and maybe
| do it less.
|
| Or failing that (honestly, more likely, but at least they
| no longer have the excuse of ignorance), at least maybe
| some bystanders will be wiser to the phenomenon in the
| future an be better able to recognize a tool for what they
| are on first sight and not grant them the time of day by
| bothering to get into any arguments with them. IE,
| recognize that peculiar form of mental Turet's and thereby
| feel no attack from it, and feel no need to defend against
| it.
