Agreed. I think this is the main reason that men get accused of "mate guarding" so much.

Protecting "your" women is hard
wired from tens of thousands of years of tribalism and conquest.
This is the reason women are so soft on immigration. When they were conquered, they got to live - albeit as sex slaves to their conquerors. But their (new) offspring survived. The men were all slaughtered and their offspring were killed. A permanent end to their line.
