Just to clarify since OP seems a bit confused himself. The granny made the incredibly mild comments about the councillor resigning as comments on both public and private Facebook posts, in response to the private WhatsApp group chat messages the councillor sent being leaked publicly.

That's the still active councillor of the ostensibly more progressive UK party in a WhatsApp group called "trigger me timbers" wishing conservatives voters would die and laughing at them getting hit by trucks. The granny who got the stasi treatment just went on generic local Facebook groups and said he should resign for that.
