If your eyes are good, your whole body will be full of light. But if your eyes are bad, your whole body will be full of darkness. All ideas are seen as controversial. It is probably impossible to make any assertion that will not find some supporters and some detractors. The problem often is that there is no indication of the quality or quantity of argument in support or opposition.
Information sleeps with lawyers.
In a world where there is no longer any truth, all presentations are adversarial. Find someone with the opposite opinion. This creates crises in values where values and ideals developed over thousands of years are counterbalanced by the opinion of one kook or rebel, with the implication that both positions are pretty much equal. Woe to those who call evil good and good evil, who put darkness for light and light for darkness, who put bitter for sweet and sweet for bitter. Anything in great demand will be counterfeited.
