Who said anything about a fight?

The West, particularly the English-speaking part of it, embraces individualism because of its cultural inputs. Nobody wakes up one morning to say they are going to be an individualist; no group from a collectivist culture resolves to place more emphasize on the group over the individual.

Humanism is a whole different thing that derived from a philosophical tradition.
