The family of a university student who took his own life after video was shared of him shouting at drag queens in a Brisbane library, has implored other young people involved in politics to seek better mentors.

University of Queensland student Wilson Gavin, 21, died earlier this week — a day after footage emerged of him and other members of the UQ Liberal National Club (UQLNC) taking part in a rowdy protest at an event involving drag queens reading stories to children.

The UQLNC was disendorsed by the party late last year.

"To young, politically motivated people of all persuasions — we implore you to seek kind and wise mentors who will guide you, and not use you or wash their hands of you when you no longer serve their purposes," his family said in a statement.

"Wil worked tirelessly for causes without personal gain, gratitude or in some cases, loyalty."

After the protest, Mr Gavin, who was the UQLNC president, said on Facebook the club believed its actions aligned with those of Queensland LNP Opposition Leader Deb Frecklington.

Ms Frecklington had earlier made a Facebook post about a high school's unisex toilets, slamming them as "lefty PC garbage".

But Ms Frecklington distanced herself from the actions of the UQLNC.

"Last year the party resolved to disendorse the UQ club and as such it is not affiliated in any way with the LNP," a spokesperson for Ms Frecklington said.

"The club does not represent our views and values."

After the video of Mr Gavin and the other UQLNC members was shared online, the group received a barrage of criticism, including from elected members of the LNP.

"To those who are now regretting words said or typed in anger that may have contributed to another person's suffering — we know and share your pain all too well," the family's statement said.

Family sends support to LGBTIQA+ communities

Mr Gavin was remembered by his parents, Michael and Bridget Gavin, and his sisters, as a young man with compassion and a sense of justice — qualities they said were among the "many things he got right".

They also addressed the controversy in which Mr Gavin became embroiled head on.

"To the LGBTIQA+ communities and Rainbow Families Queensland — we love and support you," his family said.

"To anyone who is or was angry with Wilson — we know he regularly got the "how" wrong and occasionally got the "what" wrong. This made us angry with him too."

Mr Gavin's family also said that contrary to the opinions of some shared online, Mr Gavin had not been a "deeply troubled young man".

"We remember him as a devoted and loving son and brother. We will love him, always and will be forever grateful he was part of our family."

The family also thanked police and emergency services for their compassion.

Petitions lodged with council

Two petitions have been launched on Brisbane City Council's website to ban the Drag Queen Story Time events.

Another has been launched calling on council to keep the events.

Lord Mayor Adrian Schrinner said he wouldn't comment on the specifics of the petitions until he had read them.

"I'm not aware of the language, but I want to stress again, Brisbane is a tolerant and diverse community and we need to do what we can to protect that and to support the tolerance and diversity in our community," he said.

"This is why we run a whole range of events and festivals including in our libraries, to support a tolerant and diverse community, that is what my team supports and that is what we will continue to support."
