The Miss Universe pageant was rigged to crown her and then emotionally destroy her by taking the crown away ... that's what Miss Colombia is now suggesting.

Arianda Guitierrez has broken her silence with a bang, addressing the speculation that Steve Harvey's gaffe was intentional to create some heat and boost ratings for the pageant. She says, "If that was the goal, they succeeded."

Miss Colombia also thinks the antics were a slap in the face to her heritage, saying, "It was very humiliating for me, but also for the whole country and for all the people not only from Colombia but the other Latinos that were in the auditorium."

Her comment underscores what pageant insiders told TMZ ... that there was racial tension between the Latina contestants and Miss Philippines.

Arianda also addressed TMZ's story ... that Vivid Entertainment offered her a million bucks to do porn. She says no way, adding, "my parents would kill me."
