VFR for a helicopter is enough visibility to stop before you
hit something.

The same is true for an airplane. The difference being that a) helicopters
are able to fly at arbitrarily low airspeeds, and b) helicopters can
actually be brought to a stop mid-air.

No one is saying that helicopters can fly in any weather, least of all me.
But that's not what this thread is about. The question is simply whether
helicopters can fly in lower visibility than airplanes, and clearly the
answer is yes.
