Everything is not fake. Some things are real.
Everything is not a lie. Some things are true.
"They" don't always lie, some of them lie some of the time, others lie most of the time, and a few lie infrequently and are sincerely distressed when in error.
Refrains of "it's all lies" & "everything is fake" on facebook were one of the most disturbing things about the place. It's not like people don't know something is broken. They see it, but some seem to think it's everything.
