Yes you are trolling.You fit the definition of a internet troll to a tee.You come onto a forum,where enthusiasts meet and talk about their shared interest,baiting people into arguments by talking negatively about the very subject that brings everyone here.That fits the bill of "internet troll" to me.
Maybe its you who has the guilty conscience,I am willing to bet that you have MAME and a full set on the very PC you are typing these posts on.
Lighten up a little.Life is far to short to have meaningless,petty internet arguments.Maybe you should try re-focusing this anger to a worthy cause.
