What is that supposed to mean?

The predictions that GR makes and that can be derived from GR have been 
confirmed in numerous other experiments in the 100 years before this one.  
If the attribution of the LIGO observations to GR is “spurious”, then all 
those other experiments are as well.  The chances of that are zero.

You are the one making erroneous claims here.

Yes.  Precisely, a propagating distortion of spacetime.

Incorrect.  The observed kind of strain is precisely what was predicted by 
Einstein 100 years before.  Non-relativistic strain can been excluded 
because of the precautions taken in the experiment.

There is no magic in GR.

Not in the observed way, and not under these conditions.
