Fallacies do not cease to be fallacies because they become fashions. (G. K. Chesterton, 19th-20th centuries English writer and critic)

Truth is always true, and untruth is always false. If some untruth might be accepted as truth by some, it does not thereby become true. Even though it’s politically or socially acceptable to circulate rumors (or false news), that doesn’t alter the truth. We should be very careful, not only to recognize falsehood, but always to share truth.

An honest witness tells the truth, but a false witness tells lies (Proverbs 12:17), Therefore each of you must put off falsehood and speak truthfully to your neighbor (Ephesians 4:25).
