Join a political party that isn't the Tories or UKIP!
I'm a member of Labour, and while I understand that there are many people who feel alienated from party politics, and think Labour has not provided sufficient leadership or opposition on topics such as welfare or Brexit, I believe you can still become part of a movement, engage with ideas, and influence party decisions by attending meetings (something I personally need to do more). You can join Labour or another party here:
The Green Party: https://my.greenparty.org.uk/civicrm/membership/joining
Or even the Lib Dems!: https://libdems.secure.force.com/LiberalDemocrats/NewMemberRegistration
Support or volunteer for a charity!
- The Albert Kennedy Trust provides support for young LGBT people who are made homeless or living in a hostile environment. LGBT people are at significantly greater risk of homelessness. You could mentor a vulnerable person if you yourself are sorted and LGBT, or give money to support their work: http://www.akt.org.uk/2/spg522/albert-kennedy-trust-helping-young-lgbt-people/can-you-help/volunteers/volunteer-selection-and-training.aspx
- Arts Emergency helps young people get access to education and opportunities in the arts. You could make a difference by mentoring someone aged 16-19 and giving them the benefit of your experience and knowledge. Here are the deets: http://arts-emergency.org/
- Domestic violence is a massive problem in Britain as it is everywhere. Take direct action with Sisters Uncut (http://www.sistersuncut.org/#join) and support Women's Aid (https://www.womensaid.org.uk/donate/)
- Fawcett are a good charity campaigning for equality and women's rights. Their research is particularly good, helping to influence public conversations about female representation in the public sphere. Join here: http://www.fawcettsociety.org.uk/become-member/
- Friendship Works is a charity working with children who need more social support. You could help them out financially or volunteer to mentor a kid, doing stuff like going to the cinema, and providing general support: http://www.friendshipworks.org.uk/aboutus/what-we-do/
- First Story believes lives can be changed through writing. Writers work with young people to foster creativity and improve communication skills. If you're a writer you might volunteer to help out, or you could follow them on Twitter, shout about their activities, etc etc: http://www.firststory.org.uk/about-us/
- Have a bit of a google around and see if you can use your education to help kids with homework locally. I'm coming up short but I'm told this is a thing.
- Become a governor at a school.
Help out at a food bank
You can find your nearest foodbank here: https://www.trusselltrust.org/get-help/find-a-foodbank/
Here's a slightly rusty Guardian article with some ideas for how to help in the ongoing refugee crisis: https://www.theguardian.com/world/2015/sep/03/refugee-crisis-what-can-you-do-to-help
Donate to Help Refugees: http://www.helprefugees.org.uk/how-to-help/
I'd also add that, if you're on Twitter and you're white, I think a really good thing you can do to change your own opinions and environment is start following more women and people of colour.
That's all for now, I'll update this.
