Any time gerrymandering comes up it is the tip of a very large and complicated iceberg.
But we can also look at some other things to confirm the division, things ranging from the Senate which is not subject to gerrymandering (but yes, is subject to population proportionality issues) through polling that shows both directly and indirectly, through things like historic lack of confidence in our institutions, that there is so much division and distrust these days.
There's always the issue of every generation thinking the new generation is worse, but in this case we have historical records to show that yes, things really actually are historically worse now than they have been.
So with such dysfunctional society, objectively by all of these different ways of looking at it, it shouldn't be much of a surprise that the representative body would also be dysfunctional.
