Directly weaponising emotions is very much still a thing in TTL fiction.I guess that message of love could be retained.
But not in the fantastical "love creates laser beams that can banish hate," kind of way.
More like "my love for others had made me stronger than striving for pointless material wealth" kind of a way. Love is why the people of 33 faced down a corrupt capitalist system. Love is why men like George Patton abandoned aristocratic privelege.
