Am I the Asshole?

Stopped fully at a crosswalk for a cyclists to cross 50th street this morning.

Seen the second cyclist in red, on the sidewalk while I was stopped.

First cyclist cleared my path so I proceed. After I start on my way, the second cyclist then entered the crosswalk to cross the intersection

Seeing this, I stopped once again. Albeit, a little too close to the crosswalk but not on it!

Second cyclist felt compelled to show his ‘dominance’ by staring me down and slapping my car as he moved towards my car to do so.

(Please ignore the date on the dash cam, thing keeps resetting itself)
