After carefully reviewing the thread, I concur with the observation that both Purity and Essence are acting like FGs.
However, Essence's argument is essentially as follows - by publicly calling himself the doctor he tries to establish:
1) Premise: I am the doctor because I said so.
2) Conclusion: Because I am the doctor, anyone who disagrees with me must be against me, and thus, an FG.
Unfortunately, that first premise used as an inherent assumption doesn't quite convince me. So I'll submit this vote for now.
Purity_Riot - 6 (Essence, Wardead, implosion, xdude, finkel, Flying Farenheit)
Essence - 4 (Purity_Riot, 918273645, Svenningen, Helios)
Fixari - 1 (Fixari)
