Everybody is like that the first time they go to the continent, me included
Its a honeymoon phase. Dude will get through it eventually once he studies the individual African nation he visited and sees that its very similar to home in bad ways as well as good ones. Wouldnt even matter where he touched down. He couldve visited bombed out somalia and still thought it was the most beautiful place on earth.
Im pretty sure european-americans and east asians(ironic isnt it?) who go to europe for the first time call this the "paris syndrome" or something like that. Its precursor is called "Stendhal syndrome" .
