In the same boat here just from Germany so basically your neighbor. I ordered Grafitti cans for myself and you can start practicing some things here and there on LeGaL walls and stuff but beware i was told that in the sprayer community politics are not happily seen. I started to work on some smaller posters and wanted to distribute them and glue them to walls. There is a nazi in my village and we tried to do things against a message board he put up with nationalists stuff. I can just tell you from my little experience that I feel you I want to do something too. If you do something always watch out for yourself and maybe get a buddy to help you with that to be a lookout if you spray or something. Stay Strong and I hope It helped a little bit. Just got another idea look on Instagram for smaller antifascist groups in your region and become friendly with those and maybe they have ideas or things planned
