I guess we're at "it's your fault for having eyes" part of the defense of the action.

It seemed pretty blatant to me if you watch the whole video, the chest pound and the clear arm/hand extension really makes it difficult to see as anything else.

It was distinctly different from the stills of other politicians waving that often get used as comparison by trolls trying to defend it... when you compare videos the difference is not even questionable.
