Meanwhile, I'm posting in good faith, and I think I'm holding my ground pretty well.

It sounds like you are posting in good faith. Just go easy on the "but I'm winning! lolz, groupthink!" stuff, that tends to be a tipping point.

I do recommend you look a bit closer at what people are telling you about 'evidence', it's important. I have been involved with communities in which finding clever ways to say "That isn't evidence. Where is your evidence?" in response to any given piece of evidence is rewarded with status and the stronger the evidence ignored the more respect is granted. This, for most part, isn't one of them. If you continue to speak nonsense and fail to comprehend those who are engaged with you you'll just be voted down to oblivion.
