RACISM & TINDER: A LOVE STORY ?

Can someone please help me understand? Serious question. My white friend was on tinder and swiped right for a black man wearing a hat. She opened the conversation with "nice hat." They exchanged some "pleasantries," but when she didn't respond for 15 minutes because we were at dinner, his responses got ~*intense.*~
  1. This was copy-pasted about 15 times. Not an exaggeration.
  2. I personally feel like it was male ego/anger at her apparent "dismissal" (by failing to respond fast enough) using the guise of racism. Am I totally off base? He brings up interesting points, but totally unprovoked and he makes major assumptions about her...
  3. Help?
