That is the (his/her) big picture. If you (in general) didn't back him/her in the corner by calling him/her a troll, you might get some answers when asking for details. Don't think that is an option now.
But that's it for me. I wanted to point out another perspective and I did. I don't feel the need to "convert" anyone or to be @roedi's advocate.
Just think twice before calling anyone a troll.
