For example, that line of reasoning would go: Damore saw practices he feels are discriminatory based on the available evidence. His silence could be mistaken for agreement. He should not be forced into that kind of debate at work.
Finding the approaches and views that are most coherently grounded in reality is obviously a continuously difficult task.
We shouldn't treat people poorly just for being wrong, unless their expressions of views is actively harmful. Making that determination can also be very difficult.
Lastly, as a slight tangent, no human knowledge is or ever will be 100% certain and robust (although in some specific domains we can attain incredibly high confidence). We should keep this uncertainty in mind when we act.
