You’re being absurd. Cleanliness was not what it is today. Even in war marches more died from water born disease as recent as 1800s just trudging rather than war itself. This is our history and how some of our lineages may have been entirely terminated.
Bring oblivious to this is actually really insulting for some who know very well what it took for our own lineage just to travel to safety.
It absolutely was not a walk in the park like you’re selling it. Some people were hunted for years before getting safe.
