"Above all, avoid false accusations and the distortion of truth regarding your neighbor." - Francis de Sales
When one keeps repeating an apparent innocuous, albeit factual statement about another - to suggest something untoward about that person's character - it amounts to innuendo, bordering on detraction, and dangerously close to slander.
"Refraining from imputing imaginary faults to your neighbor, from revealing those which are secret and from exaggerating those which are obvious." - S. Francis de Sales
To do this in retaliation for an offense - real or imagined - doesn't make a wrong right.
Many of us online have been guilty of this. It is better to avoid giving any credence to such writers - myself included.
