It continues to have prominance in our society due to inertia and the fact that some people want a positive legacy to endure long after they pass regardless of whether or not they did anything in life to deserve that kind of legacy.
As the person you're replying to wrote it better than I ever could I'll write what they just shared becauase I think it's worth repeating, "taking inventory is harder than eulogizing or denouncing. But it’s more honest."
We should strive for honesty in these kinds of discussions over sensitivity.
Now, Adams had plenty of opportunities to defend/explain his comments on certain issues, and he did not satisfy many people with those or perhaps dug himself in deeper (I myself really only know him from Dilbert in the 1990s, and am only superficially aware of anything controversial he did/said outside of that).
But I don't see anyone saying anything about him now that was not being said when he was alive.
