Usually in troubled areas, the men fight and the women and children flee, or they flee together as families. Yet the 'refugee' crisis of recent times was different. It was young men who were coming to the Western countries. Why is this?

Because this was never a legitimate refugee crisis. It was a planned migration with the intention of destabilising the host countries, destroying any sort of cohesive national identity and on enacting genocide the white majority.

That the genocide was to be across the spectrum, with enforced discrimination, brainwashing, quotas, and various other control mechanisms combined with anti white violence does not stop it being genocide.
