But you are aware that there IS a town that IS called Dortmund in Germany and that it therefor IS valid to assume that Sverkerman was reffering to this town. And with this it IS valid to give him this suggestion ? I kinda guess you are not, because otherwise you wouldn't have called it trolling nor provocation.
So... as a matter of fact, I doubt you are in the position to judge my comments, when you apparently clearly label them as something they are not, because you did NOT understand them.
But if you can be a bit more precise in what you call trollish or blatantly provocating, I will gladly comment on that aswell.
