Find like minded people, collective action is always stronger than individual action. If you don't currently have a community that is engaged, consider joining a Unitarian Universalist congregation. Unitarians in the US and Europe resisted the German Nazis by creating documents and providing refuge for Jewish people fleeing the Holocaust. Many congregations today have active social and environmental justice groups, often focusing on local action with low barriers to entry. Nobody is expected to believe any particular scripture, but UUs have a common set of principles, the first being everyone has inherent worth and dignity.
I visited the local queer bookshop today and left with an invite to a local queer hike and a lead on sea shanty night at the local bar. Put out feelers, talk to people, and find like-minded folks around you.
Yeah, I've attended some UU stuff, and they're by far the best of the religious groups I've looked into. But the spirituality is a bore and I just plain don't believe in 'worship'. Give me a 'church' without a god, please — just good advice, good conversation, people who aren't monstrous, and maybe a potluck on Thursday nights.
If you speak with UUs, many of us would say we are also not really into religion 😆 my congregation has a number of firm atheists. A lot of the sermons are more about human values, finding lessons from history or science, and lived experiences. However, we do tend to celebrate high holidays from numerous religious traditions. It's highly variable across congregations though. My big draw other than collective environmental action is the music program.
That sctually sounds great. I'll look into it. I'd be surprised to find myself associated with any religion again but for the right one, I guess why not.
