meditation on the term "humanism"

So, I'm a humanist by most defintions. However I object to this term on the grounds that humanism is not practised by the majority of humans. Therefore it is a misnomer as an objective sentience would consider "humanism" to be that practised by the majority of humans, which is the definition of the term "stupidity".

Surely the enlightenment values currently referred to as "humanism" should be more appropriately termed "transhumanism", in recognition of the fact that those who respect such values and regard them as the architecture of civilisation have transcended the animal motivations of the rest of humankind and embraced rationalism and human egality.
