"I wish we had more people who spoke truth to power and made statements like this - "The Unbelievable Story Of Why Marlon Brando Rejected His 1973 Oscar For 'The Godfather.'" The video in the article is short and powerful to watch."
Thanks in advance :)
The expression refers to speaking what one believes to be true, especially something that might offend or criticize those in authority with the power to retaliate, in spite of the negative consequences that might result. An alternative to speaking truth to power would be to keep quiet or to say only nice things in order to avoid (unjust) punishment by the people in power.
