You're still missing the point. The reason"fact" is in quotation marks is because (like all the eyewitness accounts quoted by yourself and others either side of this debate, here and elsewhere) is precisely that it IS anecdotal, and cannot be proven.

My points are simply that
1. The only indisputable evidence we have is CCTV footage of a man leaning over, pointing a finger, grabbing a child and the child's mother responding with fury. People have tried to whitewash this with various straw man arguments that detract from the fact that this is clearly what happened. 

2. The mother can be trusted to know the age and gender of her child (ie NOT an 8 year old, and not a boy).
Anything else is simply speculation and appears to mitigate his offence by blaming her for a crass but (imo entirely comprehensible) response.

I'm glad at least you, unlike many of his defenders, agree he is a vile excuse for a human being.
