If you've watched Marvel's "Loki," you know all about the "variant" threat. In a nutshell, variants are alternate versions of individuals created by deviations from a central timeline. They are strictly guarded by the Marvel universe's Time Variance Authority. Per their policy, any variant or parallel timeline must be eliminated under the pretext of avoiding a cataclysmic war among the offshoots. The premise is reminiscent of the worst challenges to religious pluralism and freedom around the world. Dissenting or "offshoot" views, it is argued, must be eliminated lest they destroy a country's identity, way of life or national security.
