Kendra Lust has a huge bone to pick with K.C. Royals G.M. Dayton Moore -- claiming the baseball honcho is dead wrong about linking porn to domestic violence.
Lust -- AVN's reigning "MILF Performer of the Year" award winner -- came out swinging hard against Moore ... claiming she's sick of people blaming adult videos for their problems without a shred of evidence.
"In all honesty, I think that porn helps keep people's relationships healthy," Lust says.
"It helps keep [people] safe from maybe going out and being unfaithful to their spouse ... it helped my life a lot."
Lust slams Moore's insinuation that porn is dangerous like booze and drugs as a "cop out" -- and says he needs to support it ... instead of demonizing it.
