Not a physicist either, but I think "local realism" is a conjunction of "local" and "realism". Bell inequality experiments show that "local realism" is false, and so we have to reject either "local" or "realism", but we don't necessarily have to reject both.

Best i can tell local realism basically means that if something blows up at the other side of the universe, it should not affect whatever is happening on this side until we can observe said event via the reception of energy/particles from said event.

Well that's the problem with local realism. All sorts of things do affect local conditions at a distance. If entanglement between particle pairs is not affected by any of the physical forces as described then whatever happens between them is just a matter of fact, but no where have I seen this mean we'll ever get ansibles or teleportation. It just means the universe as a substructure we're not fully able to grasp and that it may be just one of those things that connects everything despite the appearance of separation of objects and states.
