phrase-requestssingle-word-requests

Is there an English word for an idea or policy that receives widespread acceptance not due to approval, but because opposing it requires immense effort or risk?

For example, a company's CEO introduces a diversity program which will clearly disadvantage all of its current employees, but no one objects to it in fear of the being called racist.

What can one call such a policy?

Best Answer

In politics, the idea could be called a third rail.

The third rail of a nation's politics is a metaphor for any issue so controversial that it is "charged" and "untouchable" to the extent that any politician or public official who dares to broach the subject will invariably suffer politically. The metaphor comes from the high-voltage third rail in some electric railway systems.

Note: the example you gave in the OP might be something different: Doing something because it is right even though it is unpopular. That is sort of the opposite of what I am answering, which is not doing something because the opposite is popular.
