RedMercury is such a strange phenomenon to me. Everything about his posting style just screams "bad faith", but the mods let him get away with it despite a few I speak to outright believing he's a troll. It literally fits in with the "you can say anything as long as you word it nicely" thing that Era by and large seems to reject, just on the part of the spectrum that they agree with despite the absolutist nonsense making them look like psychopaths to any outside observers when you actually break down his posts.
Hell, other insufferable posters like Weltal Zero are even wising up to his schtick it seems. It just seems like a bad idea to let him do whatever he wants, but hey, not my site.
