I believe those other 2 posts are still up and probably should be deleted as this thread is the only one with additional posts on it and is already in the "Complaint Department" section of the forum. Below is my breakdown of the OP's post. As you can see it's in reference to the thread's title as the OP doesn't elaborate further (other than by listing tweets).
Title, Part 1: "Mark Kern..."; the tweets appear to be Mark's, however I don't tweet/twitter so I haven't
gone to verify.
Title, Part 2: "...Firefall fail responsable..."; if my memory is correct, Grummz resigned and at some point after The9 made an offer to him for his return, which he turned down. Thus by not returning an argument could be made that he was responsible for Firefall's eventual demise. I think that would be a bit of a stretch though.
Title, Part 3: "...Trump public supporter."; just because someone voted for Trump doesn't mean they're a public supporter of that individual. As I mentioned above I don't tweet/twitter so I can't speak to Grummz's overall public support of the current US President. However none of the tweets above back that stance. They actually appear to be a message, Grummz's opinion, to the current Democratic Party as to how to get some of their voter base back to voting for them. interestingly enough it sounds as though Grummz was a Democratic Party voter, at least for Presidential elections, but didn't do that this past Presidential election. Also there is no mention if Trump was the only Republican Party candidate he voted for as there would've been many other elected positions on the ballot (state, county, city).
So IMO, the OP is either being disingenuous and making an attempt to fracture the current forum users base/support for Em.8ER...or...just plain trolling to watch the fire and eat popcorn.
