## Political activism

The son of Martial Law era activist and later University of the Philippines President Francisco Nemenzo Jr, he has himself had a long history of political activism. He was a member of the Student Christian Movement of the Philippines.
A UP student leader during the time of martial law under Ferdinand Marcos, he was shot in the back during the infamous Welcome Rotonda rally shootings of September 27, 1984 and almost died from the single M-16 bullet that pierced through his body. Fellow activists attribute his survival from his wounds to the fact that he was a runner. He was known for his athleticism and healthy lifestyle in the campus.
He was also a founding member of the activist musical group "Patatag".
In recent years, he has strongly denounced the red tagging of UP students who have taken a stand against authoritarianism in the Philippines.
On January 19, 2020, he spoke at the protest demonstration against the Department of National Defense (DND)'s unilateral termination of the 1989 UP-DND Accord which requires the police and military to notify UP officials before they enter UP campuses. During the protest, he declared that academic freedom and "UP as a safe space and a zone for free thought and free speech" have to be defended at all times.
