I read the whole back and forth from the pdf and it is really insane and of no help to that community to have someone with that mindset being in charge of a place where he could be disseminating useful information and valuable tools to those with lung diseases such as a COPD "support" forum.
What a waste.
It's unfortunate that anyone on e-cigarette related forums with COPD will have to use another account or risk being marginalized a la Nazi/McCarthy conspiracy and not be granted membership in the community. But there really is nothing you can do but back the hell away after someone starts in on the conspiracy theory.
