Yes, but to say 'atheists believe in Secular Humanism' is to use religious language and might be seen as using a religious use of the word belief. It would be more accurate to say that 'secular humanism' is a world view accepted by many atheists.

I see myself as secular and would be happy to be called humanist, but I don't 'believe in' secularism or humanism. I don't believe in anything beyond what can be justified by reason and evidence, but I'm strongly inclined to favor both.
And the Council for Secular Humanism seem a bit nuts to me...
It seems to be defined by pretentious gobbledygook.
