These ethical issues have in common that they are all swirling in emotion, and they are all powered by deeply emotional thinking. They are not easily solved issues because they really don't lend themselves to reasoned solutions. In spite of the bad fit with reason, reason is used by proponents of both sides of these issues to justify what they are advocating.
But the real truth of all these issues is that we are looking at illusions. While these issues are presented as having two sides and vigorous enthusiasts for both sides, the reality is that the two sides are not opposites but orthogonals -- they are not facing each other, they facing in completely different directions -- and that's why solutions to these issues don't appear.
Because they are deeply rooted in emotions, and because the opposing sides are really orthogonals, not opposites, these problems will not solve by finding common ground. They will solve instead by becoming irrelevant -- they will decline and die as they are replaced with other issues that fire the community's emotions even more.
"Is a woman's place in the home raising kids?"
"What kinds of rights should a serf have?"
"Who should have right of way on a street, a horse and buggy or a horseless carriage?"
These are examples of burning questions that have been swept away by the changes in how we live. Our current burning ethical questions will have the same fate as humanity's lifestyle changes in the future.
Irrelevance is the ultimate fate of all ethical issues.
