MANILA, Philippines — Author Ma. Ceres P. Doyo won't mind showing President Rodrigo Duterte books and offering him movie suggestions about Martial Law if it helps to make him aware they exist.

As far as literary works are concerned, Doyo said she knows hundreds of them.

Duterte on Friday said allegations being hurled at Ferdinand Marcos by critics couldn't be proven either way.

"Whether or not he performed worse or better, there is no study, there is no movie about it," Duterte said. "It’s just the challenges and allegations of the other side which is not enough."

Doyo, a social activist whose op-ed stories appear regularly in the Philippine Daily Inquirer, said Duterte couldn't be more wrong.

"I have a list of more than 200 books on Martial Law and I might put it up on a website so a lot has been written about the cruelty, the tyranny of the Marcos dictatorship," said Doyo, who was on the dzMM program "Teka Muna" on Saturday answering questions about Marcos' burial at Libingan ng mga Bayani.

"Why would President Duterte say all of a sudden that there aren't any movies about Martial Law? 'Kapit sa Patalim,' 'Sister Stella L,' 'Dekada 70,' to name three only."

Doyo said the Marcos burial stunned her, but added that "if you know the Marcoses, it's like you wouldn't be surprised anymore because that's who they are, duplicitous."
