I won't quote/reply but sometimes their sh1t is so egregious it needs calling.
I genuinely don't know why it does, unless it's in a court of law, or in a scientific publication. The aim is simply to provoke a response (or better, outrage), and lying brazenly and invoking egregious & outrageous things are the means. The best response is none. I appreciate it can be hard to resist, as it looks like an easy, open goal ("This simply isn't true, and here's the irrefutable proof!"), but the response itself (not the content of the response) validates the egregious shît posting, as far as the poster is concerned. It's a basic feature of trolling, nothing unique to NCAP and a particular poster.
