Pakatan Harapan is so desperate to win in the forthcoming 14th general election that it is willing to sacrifice its principles against racism and authoritarianism, UndiRosak campaigner Maryam Lee has claimed.

In an interview with the weekend edition of Utusan Malaysia, Maryam said the inclusion of Bersatu as a Harapan member had destroyed the opposition pact's legitimacy to change the country's political culture.

She also said so long as the opposition practices politics of obsession, idolises their leaders and makes use of religious sentiments, there will be no progress in the country's political culture.

"When the leaders are practicing such toxic politics, then it is comes as no surprise that their followers are also equally obsessed and will bully anyone with a different view," said Maryam, who recently lodged a police report following online attacks against her.

The UiTM graduate pointed out that issues such as housing, minimum wage, education and medical facilities should be brought front and centre, but become drowned out by the infighting and bickering between Harapan component parties.

She said this when asked for comments over her criticisms of the opposition, which led to some labelling her as a government sympathiser.

Maryam had recently published a video on her personal Facebook wall showing doctored images, sexist comments, and accusations that she was "paid by BN," which she received after participating in a Jan 25 forum discussing the UndiRosak or spoiled votes campaign.

She blamed Harapan supporters for the attacks, and condemned leaders from the coalition for their "silence" despite previously decrying "toxic politics."

Leaders from the coalition later denounced the misogynist and personal attacks.

Commenting further, Mingguan Malaysia also quoted Maryam as denying the perception that she was either pro-BN or pro-opposition.

"My political stand is based on the principles of democracy, justice and people's prosperity.

"Whoever I view as going against these principles, I will criticise them," she stressed.

The UndiRosak movement, which began on social media, has gained traction in recent months, especially after politicians from both BN and Harapan spoke out against it.

Prime Minister Najib Abdul Razak had described the "spoilt vote" campaign launched by certain quarters as an action that contradicts the democratic system being practiced in Malaysia.
