Clearly it isn't Darwinian selection, because it can favour transmission of genes which are not conducive to survival.
Clearly it isn't variation, because it tends to reduce the degree of genetic polymorphism within a population.

This is the one thing that Darwin got wrong: he thought that the unit of selection was the organism, but it's not. The unit of selection is the gene. Richard Dawkins is the one who figured this out. Meiotic drive is not Darinian selection, but it is selection. But Darwin could not possibly have known this because genes were unknown at the time.
