I agree with you up to a point. And that point is the volume of water that is discharged. It has nothing to do with the brine itself (although, as you point out, there are "some" people who say so -- but are never identified or sourced). But if the discharge volume of water is too much for the septic, then damage could occur from the overflow. For example, if you have a system that was perced for 3-bedrooms, and you have a family of 8, you might be at the limit (or even over) for the septic. So if you then add a water softener that backwashes every 4 days, you would definitely be in trouble.
But again -- it has nothing to do with the brine itself, although that's what is used to scare people.
