@emilyava this is completely correct - George Soros’ Open Society Foundation do fund all kinds of projects - very much geared to diversity and inclusion.
There is a office in the UK.
You would need to create a sales pitch for receiving a grant.
www.opensocietyfoundations.org
Look on their site go to ‘how we work’and then grants and search through for all the money they give - one example was ‘English collective of prostitutes’2021 $110,000 to support decriminalising sex work and respond to discrimination faced by migrant sex workers.
Anything pitched at migrant help would receive particular help from soros’ foundation.
Research starting a charity so you can get tax free status.
Look for those willing to give their time and money to this. Organisational partners. Build that network - give it a clean front and put policy in place that leads to a particular end.
