In any given conflict, there would be doubt. And one side will have the advantage due to it. Like in sports tv umpiring. Whenever the image is not clear as to what the decision should be, the rules have a carve out on which side whould get the benefit of benefit of that doubt. Otherwise the game will be stuck.
In life, where certainty is much more rare, it is a good rule of thumb to handle doubts this way. By OP's own admission, they can't watch every hour and minute of Charlie Kirk's speeches, interviews, and TV appearances. But he has a clear pattern of making remarks such as this.
Why would you believe that he did not make that statement? Objectivity does not require anyone be neutral for no reason. It is reasonable to assume that the author is correct.
