Part of me is hesitant to write this out because I worry some jackass us fed will use it to harass people doing important work, but here goes. Look out for groups:

• organizing mutual aid
• community libraries, especially those providing a safe space for queer and trans folk
• people doing street medicine, working with the unhoused
• prison abolition groups, folks doing prison support
• community gardens
• folks working with migrant workers

Anywhere people are supporting each other outside of official programs and with nothing material to gain you will find anarchists among other flavors of leftists.

Canteens, libraries, community centers, LGBTQIA+ centers, free free markets, protests, punk events, syndicalist events, etc. etc. Any place you can imagine “where can I build solidarity and intersect?”
iirc, solar punk events is why !anarchism@slrpnk.net was founded by

Go to music events and shit

To be clear I am not an anarchist but if you have a food not bombs chapter near you anarchists will almost certainly be there.

Idk let me know if you figure it out. I've been slowly trying to win over my friends and family who will listen.

I'm in a pretty conservative rural area so I'm on a bit of hard mode.

I don't know lol. I'm just commenting to let you know that you're not alone. I live in a suburban area where there's no antifascist groups to speak of, and I really don't have the time or people skills to start a group from scratch.

Radical bookstores are usually a good place to start

Find a group online who meets in your locale, maybe there’s a local food co-op or something you could attend and meet people there?

Where I live, it’s common for self-managed social centers to organize cultural activities, workshops, concerts, and so on. You can search online to find a center near you that aligns with your philosophy.

Cat food seems to attract my sort of anarchists.

Here's a handy little guide on how to find like-minded folk: https://infosec.exchange/@tinker/113589807117870451

There's a significant number of them in my mutual aid group. You could try to see if there's an existing group in your area-if you are having trouble finding one you could help out at a food kitchen for a while and keep an eye on who comes to donate food regularly or chart with other volunteers about other groups they may be a part of. You could also see if there's a DSA (or similar for your country) chapter and ask some of them if they know any other groups that might be more in line with what you're looking for.

At least in my mutual aid group a lot of people volunteer at multiple orgs from food kitchens, animal shelters, clothing upcyclers, bike repair, etc.

You could also try to arrange a book club for something like Dean Spade's "Mutual Aid: Building Solidarity During This Crisis (and the Next)."

I've met anarchist at demos, after attending a few I was invited to public meetings then to closed meetings.

Essentially if you are practising anarchism then you should meet anarchists.

You can try to find something for your region in the links of that I had made about movement-related event calendars

You seek out their orginizations and pay club dues

Folkpunk shows.

"Anarchist seeking organization" is my favorite find from All today.
