I'd love to see that prospectus:"the children here are random collections of genes with no meaning and no purpose... we believe in the survival of the fittest and to the extent children and staff build a real school community it is only because that what works for survival...."
That has to be one of the most offensive remarks I've heard on either this thread or the other one.
Either you are really trying to be offensive or you really have no grasp of what humanism is or even what survival of the fittest actually means.
Just in case you genuinely don't understand It refers to species evolving so that those with the changes most suited to their environment (ie most fit for purpose) survive longer/ procreate more etc which in the long term results in changes to a species to make then survive better in their environment. Its why people living in hotter countries have darker skin. I'd like to think that your god wouldn't have a problem with that? 
Humanists like myself (I can't speak for every one) believe that the good and bad that happen in the world is down to the choices that people make (and luck) and that if more people make good choices on the whole the world will be a better than than if they make poor choices. In my mind that is more conducive to developing a strong community than believing there is an outside influence which controls everything (to some degree or other) which you cannot influence.
It doesn't make me consider the catholic religion in a positive light when proponents of it seem to lack the ability to understand that people without a belief in a god can be every bit as community minded, fair thinking, ethical and public spirited and yes even as kind as any other person who does believe in a god.
