" ....and yet the atheists here feel certain enough to mock the Christians here , and the more so if they are creationist."

No-one mocks Christians merely for being Christian. Christians who try out loud to claim merit for their beliefs, or who justify malpractice such as forcing religion on children, or who post on secular websites offering or asking for prayers, or who moralise at people, about abortion for example, in the name of God, are fair game for mockery, and, if mockery's all they get, they should consider that they've been let off lightly. Creationists are all idiots and they deserve mockery just for being creationists. No religious belief deserves any respect at all. The best that honest-to-goodness believers should hope for is silence from critics as long as they themselves keep their beliefs strictly to themselves. That's a respectable stance, even though their beliefs are not respectable.
