I completely agree; you're right, although it may sound simple, it is indeed a complex matter.
Philosophically, I believe the best way to counteract bad speech is to encourage more speech. Moreover, I strongly feel that censorship has contributed to growing anger among people, as it not only restricts the understanding of diverse thoughts but also makes individuals feel powerless. History has taught us that when peaceful means of protest are removed, people tend to resort to violence.
In my opinion, the optimal approach would be to give users full control over their own experience and hold them accountable for their own words.
While there may be bad actors, this approach remains superior to our current one imo.
