Concern trolling is basically when you pretend to care about an issue in order to undermine and derail any measures that would be taken to address the actual, underlying problem that’s affecting society.
I've been at this skeptical blogging thing for over a decade now. I realize that I periodically remind you, my readers, of this and that perhaps I do it too often, but my reminders generally serve a purpose. Specifically, they serve to put an exclamation point on my surprise when I discover a new purveyor of pseudoscience and/or quackery that I had never heard of before but who is apparently fairly well known in the quackosphere.
