Everyone has a line.
Some are drawn boldface in red for advance warning, others are thin, blue or dashed to be regarded as inconsequentially permeable.
Most dangerous are those invisibly inked to ensnare freedom’s advocates, all unbeknownst to them until it’s too late. They adjust positions of their lines without warning by personal convenience depending on a perceived threat to their narrative. Their unprincipled advance or retreat serves the purpose of censoring and punishing antagonists who innocently stumble across and into a web from which few escape.
Everyone has a line, the crossing of which merits no forgiveness nor good reason for it to exist in the first place.
But they do and they are the grounds on which freedoms breathe their last.
