Kenya Moore -- Bitch Fight With Porsha Was Hard to Watch

Kenya Moore told our photog ... the epic "Real Housewives of Atlanta" brawl between Porsha Williams and herself was "disgusting" to watch on TV.

Kenya was tight-lipped on Porsha's glamorous mug shot -- taken after she was criminally charged with battery, but she did say she'd love to see her nemesis replaced with someone less violent.

It's also interesting how she responds to the $64K question ... whether she'll return to the show next season.
