Here I was thinking the all caps was the give away
No point putting on that "pretend angry" when there's really nothing too bad about post to start with. I mean it's not like is suggesting some "new game rule" that goes against what SWSE is and would turn it into a completely different game.
Now if someone were asking a game related question and I gave a "HELL NO!" then that's probably serious although I'm also likely to elaborate on it more if time permits. Unless of course it's so out there it may be impossible to respond to with any kind of reason.
PS. Now maybe I am talking about the EVIL PERSON who does that put channelling that past you and to the source of those things. It's a little like being unhappy about something and then "being hostile" to the delivery person or customer service rep who (most likely) has nothing do with the source of your displeasure.
