> the way to express those arguments should be a public speech or writing, not in a way that causes actual harm to others
The assumption here is that expressing those arguments as public speech or writing does not cause harm. I think this is wrong. Arguing for extermination of the Jews did, in fact, cause harm. Bullying someone into suicide does, in fact, cause harm. Spreading propaganda can, in fact, cause harm.
