Protection from red on a red creature is one of the strangest self-referential pieces of design red has ever printed. The keyword's usual job (dodging burn, walling a color in combat, slipping past targeted removal) cuts hardest against the very deck that would run this body, because red mirror matches are exactly where a clean 3/2 that cannot be Lightning Bolted earns its keep. It cannot be blocked by red creatures, cannot be targeted by red spells, and shrugs off red damage entirely, which turns it into a soft lock against the most efficient removal suite in the game when both players are reaching for the same color. The cost of that resilience is how narrow the window is: against any other color the protection does nothing, and the 3/2 reverts to a vanilla beater that trades down to most anything. That is the tension the design is built on. It is a sideboard answer wearing a maindeck creature's clothes, a card whose value swings wildly depending on whether the opponent shares its color. The flavor lands cleanly too: a Mirran holdout standing against the red-aligned forces overrunning its home, immune to the thing that would burn it down.
