Well now as we are beset with a constant barrage of fake news would not you prefer that the purveyors of fake news be guided by the Commandment; You shall not bear false witness ?
Well I personally feel it wrong to lie and I came to this though reason and logic without the need to be commanded to do it.
As for the purveyors of fake news they are beyond being guided by reason and logic or any commandment to tell the truth.
