Why Freeza discriminates against Saiyans?

Is the any particular reason? Apart from being afraid of Super Saiyan legend. Judging by the way he talks, its obvious he has the opinion that Saiyan are a savage inferior race.

Saiyans remind me of Uchihas as far as them being overpowered in Dragon Ball’s and Naruto’s respective universes.
