I’m asking for data on harm, we may assume it’s harmful, but how harmful? Can it even be measured? These are interesting questions.

Who judges what's disinformation? In the case of holocaust denial, you have historians who can easily disprove the deniers. What the hell is Google's claim to credentials?

In terms of harm measurement, it's not as straightforward as you would like. Are we judging feelings or violence that results or...?

Next, end goal. You want to squash every individual who denies the Holocaust occurred or downplays it? Good luck, you'll have your hands full in countries like Pakistan and Saudi Arabia and Iran.
