For example, this poster to not be named, would like to think they participate in serious discussion, but only where they believe they could not be proved wrong in any way. If they can be, the response to them will be blown off and made to look like the one making the sentence to begin with has done something objectionable. And afterwards, they will ignore and not pay attention to the other person further, even if they were just looking for information or discussion.
Those types of users absolutely steam my vegetables.
Anyone else?
