Take the time to read the lines for they do address your interpretation...
One must expend ones breath to prevent lies that will lead to death, it is simple self-preservation.
In the moment there may be some solace in surrender, but in the long run you only manage to encourage the offender.
We do not repeat the truths to convince the one who is mendacious, but to prevent the lies from swaying guys who may not be as perspicacious.
For if through inaction the lies gain traction, both people and truth will die if power is gained by the lying faction.
