I have had discussions with individuals who maintain that entertaining (and giving airtime to) certain ideas itself constitutes harm.
I asked, “Are you advocating a system where giving airtime to certain ideas, but not including incitement, would be punishable?”
They answered in the affirmative.
The justification being that entertaining certain ideas itself constitutes harm (because entertaining ideas may be proximate to harm or “increases the likelihood of harm”).
We also got into definitions of “harm”, which, in my view, were expansive. (In the sense that nearly anything could be rationalized as resulting in harm.)
