An inner city community group which openly challenges extremism was among organisations praised by Home Secretary Theresa May during a visit to Birmingham.
The Upstanding Neighbourhoods group told Ms May about its work including the time activists quizzed and challenged radical preacher Anjem Choudary during a rally in Small Heath earlier this year.
Co-ordinator Kashan Amar said they had a network of 50,000 people who were helping to counter ISIS's hate-filled messages and other extremist groups.
Following interviews with hundreds of young Muslims in Sparkbrook, he said they had also built a profile of reasons why people were attracted to extremism.
Mr Amar said: "Religion is not very high up, it is just one of a number of factors, 15 in all, which also lead to substance abuse, sexual violence, guns and gangs."
The group's "Say No to Anjem Choudary" Facebook page has thousands of followers dedicated to challenging the preacher's narrative.
Mr Amar added: "We challenge him face to face when he comes to the city.
"He held a rally in Coventry Road during the election campaign. We had seven or eight people go down to challenge him - in particular, his claim that voting is anti-Islamic."
While meeting a wide range of groups at the Custard Factory in Digbeth, Ms May launched a new campaign for the Balsall Heath-based Odara network which offers advice and confidence-building support to women of all backgrounds.
The help ranges from supporting those who want to set up businesses, holding coffee mornings and helping individuals struggling with mental health problems or abuse.
Co-ordinator Aysha Iqbal Patel said: "We also work to raise awareness of extremism, grooming and abuse. There are still many women who aren't aware of those risks."
The Home Secretary is to launch a new strategy in the autumn to tackle all forms of extremism, from Islamist groups like ISIS to neo-Nazi organisations.
She wanted to meet grass-roots organisations to discuss that strategy.
Ms May said, although the Government was looking at introducing disruption orders to tackle some groups, legislation was not the only answer.
She added: "It is about groups, as we have seen today - people in their communities, volunteers coming forward, working together in partnership because the Government can't do this on its own.
"It is important we tackle all those people who are trying to put barriers between us."
