You might be right, still scaring potential new players doesn't help the game.
Unless we are talking about kids aged 2-10 years old, the truth should not be hidden, even if it's scary. Grownups can normally handle it.
And what "helps the game" is only secondary after what helps the individual player or non player to have a better understanding of things, thus becoming able to make better choices in his life. This is another reason to state the facts and not hide them in a selfish manner to keep the game we are so addicted to alive and running for a bit longer.
