The answer is NEVER, because if you do and it becomes common place, you will have creationism being taught in science classes, revisionist history being taught as actual history, lies taken for truth, feelings being rated as more important than facts and world descending in to kakistocracy as silly platitudes are peddled as wisdom.

Excellent

How true!
