It probably has something to do with the forum rules.
"We ask that the users of this board treat one another with respect, even when opinions differ. Personal attacks that are intended to cause unwanted attention, embarrassment, or harm will not be tolerated."
We ask that you deal with individual's posts, not try to psychoanalyze the poster's reasons for posting. Trolling is against the forums rules, so if you feel a post is trolling, please report it for the moderator team to deal with rather than taking on your self to deal with. Doing so in threads is how perfectly good threads get derailed into oblivion.
