An exception is if you have authority that will shift people's beliefs even without backup.
Another exception can be if you merely post links, and don't endorse any statements beyond that link. Then you're performing the service of providing more information, and any problems can be taken up with the original author.
But making claims and refusing to back them up or clarify on account of trollphobia is borderline troll itself.
