Yvonne Mosquito was suspended last month over allegations she visited a murder victim's family without informing officers.
But Maxie Hayles said Ms Mosquito was "an ordained minister giving condolences to a grieving family"â€Ž and a councillor for the area.
He chaired a meeting of more than 100 people to discuss the suspension.
Monday's public meeting at the Afro-Caribbean Millennium Centre in Winson Green, Birmingham, discussed community concerns over the suspension.
Kenichi Phillips, 18, was killed as he sat in a car in St Mark's Crescent, Birmingham, on 17 March.
Police and Crime Commissioner David Jamieson previously said he took the "very difficult decision to suspend the deputy PCC" with immediate effect, pending an internal investigation into potential gross misconduct.
Allegations against Ms Mosquito were reported by a "senior officer from the force" and if proven "could have potentially hindered and jeopardised a complex, sensitive and ongoing murder investigation", he said.
The union Unite said it was "appalled" more detail about the allegations "that should be private and confidential" had been put into the public domain by the PCC.
The BBC later revealed Ms Mosquito had complained about the PCC four weeks before her suspension.
There was "no connection between the decision [to suspend] and any other issues," the PCC's office has said.
Peter Pennant, local pastor from the Council of Black Majority Churches, told Monday's meeting Ms Mosquito's visit was not in her capacity as deputy PCC, but in a "church pastoral capacity".
Ms Mosquito has not yet commented.

China's leader attended a state banquet at Buckingham Palace along with his wife, Peng Liyuan, on his four-day visit of the UK.
There was chanting by pro and anti-China supporters and, during a press photo call for the Amnesty protesters, huge Chinese flags interrupted their line of vision and drumming from the groups in support of the leader intensified.
People handed out bright red 'I love China' t-shirts and the crowds coming out in favour of President Xi dwarfed those who rallied against the communist ruler.
Among Amnesty International protesters was Dr Shao Ting, a research scholar who was involved with the 1989 Tiananmen Square protest.
Dr Shao, who now lives in London, says he was protesting because if the British government follows the Chinese model, it will "push the issue of human rights away".
Amnesty, pro-Tibet and Falun Gong protesters watched on as the Mall was flanked by hordes of people clad in bright red shouting "Xi Jinping, Xi Jinping" as the politician was driven past in a gilded carriage.
Amnesty protesters say they wanted to raise cases such as that of Cao Shunli, a human rights activist who died in police detention having been denied medical attention. Her family were reportedly denied access to her body.
One pro-China group were visiting from Swansea University. They did not wish to be named, but one man says they were out supporting President Xi "because it (China) is our country - and we are so proud".
"His visit will strengthen the link between the two countries and benefit both sides in terms of the economy." he said.
The suspension of the West Midlands Deputy Police and Crime Commissioner was "heavy-handed", a meeting heard.
