She has garnered a reputation for promoting universal suffrage, rule of law, human rights, and equal opportunity, as well as advancement in the interests of women, homosexuals and other minority groups.

She also supported members of other pro-democracy political groups such as Civic Act-up, which were also contesting seats in the Wanchai district council.

The thinking was that the remainder vote on both these tickets was sufficient to return all four candidates to office, providing that voters in the pan-democratic camp were coordinated effectively.

Conspiracy theorists claim that, during the final days leading up to the election, the Democratic Party believed it could secure a seat for their third candidate, Lai Chi-Keung.

In December 2011, after The Frontier had failed to pass its own resolution to dissolve, she joined with Lee Cheuk-yan, Cheung Kwok-che and others to form the Labour Party, taking up the position of vice-chairwoman.

In 2012, soon after Ho re-elected as member of Legco, she put forward a proposal calling for public consultation on legislation to outlaw discrimination based on sexual orientation.

[1] During her terms, Ho is one of only few legislators to openly support same-sex marriage and other LGBT rights, conservative parties and groups criticised her on this issue.

On 18 April 2020, Ho was arrested as one of 15 Hong Kong high-profile democracy figures, on suspicion of organising, publicising or taking part in several unauthorised assemblies between August and October 2019 in the course of the anti-extradition bill protests.

Following protocol, the police statement did not disclose the names of the accused, however others arrested include veteran lawyers Martin Lee and Margaret Ng.
