> every law will inevitably impact different groups at least a little differently

What if a large portion of laws systematically impacts one group negatively?

Sometimes it happens. Taxation can systematically impact rich people negatively, for instance.

Right. So we shouldn't take the effects of taxation into account when making tax laws?

Yes, but just because a law disproportionately hurts a particular group is not necessarily a problem.

Correct, not necessarily. But if it is, that should be considered.
