Pie says no, RM says yes, not really any other reasons given other than RM's claim and Pie's distrust of RM. So Imma just make the decision to on whether or not to claim myself; I've gotten impatient waiting for town to come to a consensus on the issue. Plus I'm a little more confident in my abilities now that more information has come out about RM.
I'm no MMA expert but Kung Fu isn't on the list of most common MMA styles. Not from what I've researched. However, technically any martial art can be featured here in this game as Lunatic said, with CNerd's Aikido claim being one of them.
I am townreading CNerd because he is genuinely cooperating with town and the first thing he did in this game that strikes me as noteworthy is he claimed under no pressure whatsoever because he liked RM's idea. While some other townies and I had reservations about the strat, CNerd's first instinct here was to reveal what he could. This is exactly what he did in Ozark Mafia, except this time he didn't reveal his role. And yet, the pattern of outting too much in an effort to cooperate is still here a bit. He clearly attempts to contribute (Post #35), and he says he is townreading Wylted (Post #42) there but he had already outted what character he thinks Wylted is by then (Post #37). While obviously you don't want to out something like that if you (especially if you think the character is a defensive role), I don't think that makes CNerd scum, only noob town. If he were scum he would out it in a mafia PM, not to the rest of town. Given how inexperienced CNerd is at this game, I think it would also makes sense for him to make misplays like that, especially because outting too much information is the exact same noob mistake he made in Ozark Mafia. As for his increased activity, I just chalk that up to him being more enthusiastic about this game, or perhaps a tad more confident. Either way, I am not going to scumread someone for making an effort to try more. So yes, because I townread CNerd, I believe his Aikido claim.
With that out of the way, back to RM. My logic is, if Aikido, a role not common in MMA, is town, then it is plausible for Kung Fu to be town as well. I have no reason to suspect his character claim. But what about his role claim? While I don't know the reasoning as to why Kung Fu would be Justice (RM explain plz), it does explain his behavior thus far. The way he acts based on how his Role PM mentions balance along with his own role is (even his thought process follows the lines of his role, take two players and examine their relation) makes me think that there is a clear cohesion in how he is playing and he role, so yes, I believe his justice claim.
With that being said, I am going to trust his analysis and claim. I am Sambo.
