Eh, I'm not even debunking Ren on this occasion, I'm simply airing that this was a strange and rather meaningless tangent that isn't even Ren's fault, it just came about. /shrug.
As for why it usually becomes Ren vs everyone else, Ren has a pattern of forming an opinion from something/somewhere and promptly defending that opinion to the absolute end regardless of if it is categorically proven wrong, is based entirely on second hand info or is in some other way shaky at best. The guy is seemingly clinically incapable of holding his hands up and accepting defeat. At best you might get a slow and steady goalpost shuffle as seen in the 1T1H2DPS vs 1T3DPS thread. At worst you get name calling whilst crying foul.
There's a very good reason why Ren ends up with fights all over these boards, not just here. There's a very good reason why Ren has his very own impersonator. Ren has tried to take over these boards with his often inane, morose and dishonest views every bit as much as we've tried to debunk them where necessary.
Don't get me wrong, I've made some absolutely idiotic posts, comments and suggestions and whatnot here over the years, and I'm not trying to suggest that every post Ren makes is wrong either. It's just that he has absolutely no idea when it's best to just let it slide. I was one of the first to defend him on the 1T1H2DPS thread and yet I arguably ended up being the harshest of all on him over that. Because he just couldn't bring himself to own the mistake.
*edit* And yeah, not a fan of the whole silence is tacit agreement view either TBH. Ironically taking that stance is arguably a large cause of the circular arguments here.
