Facebook conversation with Christina Olsen
Roy Hanfling I finally clued in to what you said about the <g> ! Just saw it in someone else’s comment on another topic in that group. It’s a signal before escalation…signal to whom? Like a gang sign maybe. Sinister.

Christina Olsen i suppose there is a gang,
I read this article which I can’t find right now
but
They said something along the lines that having some of these beliefs were signals of affiliation, to the gang
The article suggested that believing sensible things was a weak signal of affiliation, believing ridiculous nonsense marked them as true believers
