There are many in the science community who have learned to shut up about their personal beliefs. They are paid to teach and support evolution with no choice for any other option. If its your bread and butter....who is going to make waves?
For those who do stand up, the character assassination that takes place virtually guarantees that they will have trouble getting a job anywhere. People
have lost their jobs, but their employers have made certain that they find grounds where no litigation can take place. You really think the big boys of the scientific world have scruples?
