A Native American lecturer has been found to have discriminated against and harassed a white student at San Diego State University.

A six-month investigation by the California Department of Justice concluded that then-student Crystal Sudano was discriminated against based on race and faced racial harassment and retaliation after challenging the professor's views.

Sudano reportedly filed four complaints against Native American and Chicano professor Oscar 'Ozzie' Monge accusing him of racial harassment and retaliation, and discrimination based on a disability and race, reported the university's newspaper, The Daily Aztec.

The two had argued over the university's Ascot mascot and Monge later declared that '"whiteness" is synonymous with evil'.

According to the investigation's report, Monge sent Sudano (pictured) at least 15 offensive Facebook messages, including one that threatened to lower her grade after she voiced her views about the school's Aztec mascot

According to the investigation's report, Monge sent Sudano at least 15 offensive Facebook messages, including one that threatened to lower her grade after she voiced her views about the school's Aztec mascot.

Monge has become well-known on campus as a proponent of retiring the Aztec mascot and moniker, accusing the school of cultural appropriation.

He reportedly told Sudano that her T-shirt, which bore a stylized SDSU logo with a spear through it, was 'racist' and accused her of cultural appropriation when she wore her hair in braids.

The investigation allegedly found that Monge sent Sudano at least 15 offensive Facebook messages, including one that threatened to lower her grade after she voiced her views about the school's Aztec mascot.

Monge, according to the Washington Examiner, is a vocal advocate of getting rid of the university's Aztec mascot and moniker, alleging they represent cultural appropriation.

The University Senate voted in November to end the use of the mascot, but the vote was disputed because it came just seven months after the Associated Students council voted to keep it, the San Diego Union-Tribune reported.

The student challenged the professor's views, saying that 'The idea is that everyone no matter how low on the totem pole you are, shared governance is what gives the lowest man the right to share his opinion and for that opinion to be heard.'

Monge then criticized Sudano, saying she should not use the phrase 'totem pole' and went on to criticize other students in the group, calling one an 'Uncle Tom' and others 'Frat Bros and Sorority Sisters...who do not easily empathize with non-whiteness,' the student paper reported.

Sudano was enrolled in Monge's course during the spring 2017 semester but dropped the class after tensions escalated between the two after she began to investigate the claims he made in his heralded 'Fail Montezuma' thesis.

That thesis, presented in 2015, earned him a master's degree and has since been used to work to get the mascot changed. Last November, San Diego State's academic senate, made up mostly of professors, passed a resolution calling on administration to abolish the Aztec mascot.

As for Monge, he threatened to lower Sudano's grade over her research into his thesis, the report found.

Monge denied any wrongdoing, writing to the investigators that 'It is quite easy to argue that "whiteness" is synonymous with evil.'

San Diego State released a statement about the investigation, but did not address the probe, stating only that it 'does not discuss pending matters due to privacy rights of all parties involved and to protect the integrity of the review process.'
