> because it doesn't agree with quantum mechanics

I don't think it doesn't agree. It's just that we never managed to neither formulate quantum mechanics on 4 dimensional space time nor quantize gravitational force. So we simply have no idea what happens in small scale in significant gravitational fieldd.

We absolutely know GR is wrong, at the very least because of its singularities.

All we can tell from singularities is that GR might have a realm of applicability ... like every other theory ever. Not that its wrong.

"Has a realm of applicability" is what people mean by "wrong" here. As in, the equations we have don't fully generalize and explain all regimes. The "right" model will cover all regimes and still reduce to match what we already have.

I don't think MOND dosen't agree with GR. It's just that we never managed to formulate MOND in a spacetime compatible with GR. So we simply have no idea what happens on the galactic scale in a significant gravitational field.
