It's main use would be water filtration... of which, I have no need for charcoal.
The only reason I would recommend it would be to block up lethal diarrhea. It's other use.
I wonder if that comment was too subtle. 
Far too subtle for RE. He thinks "lethal diarrhea" is artistic expression.
It's not too subtle for me, and impugning my intelligence and ability to read subtext is a violation of the CoC. I suggest you give yourself 3 days in the Cooler.

Fine. I was considering ceasing all input anyhow... just as I did with Permies when they were giving a voice to climate denialists. Their loss. I clearly have more important things to do. Food to grow. Things to build. People to save.
I'm hearing a voice, a word, from the spirits through my crystal ball. That word is "Intervention"
Too late for an intervention for RE. He's at the end stage.
But don't quit the Diner. Without the Canadians, the forum is a much less interesting place. We need you and NF very much. And Cam.
We all know RE goes off sometimes......we all do. .Unfortunately it's a damn tough time for most of us, which makes us more tense and irritable.
Nobody here now is going for anything about anything that isn't the truth. We just come at it from different political and philosophical viewpoints, and each of us sees collapse from a slightly different perspective. Plus, everybody here has unique personal knowledge and a brain that works...which can be associated with strongly held beliefs....many of which are completely valid........but not identical.
I get mad when people question my motives...especially when it's done in a way that questions my intelligence and my ability to filter through bullshit,,,,which I think I happen to be pretty good at......not talking about you....just about what makes me go all caps.
