Nothing to thank for, Oliver. It is just as it is. I would say "to feed a missunderstanding" instead. Keep your peace in your heart/mind and not allow anybody to take it from you. It is the key to keep hapiness IMO. And we do not know that guy anyway and I noticed he is putting some info in his profile, so not sure if he is really troll. But definitely if that post was mentioned to you - he should apologize for that.
