When, in any area directly affecting human beings, there exists a grave unsolved problem, and when the absence of a solution leads to many tragedies, then those who, well aware of the problem, seek to conceal or belittle its importance, may be considered morally irresponsible. Why? Because they tend to create a mood of complacency towards the tragedies, and because such complacency impedes efforts that may, at least partly, help to solve the problem.
