If you are an anarchist and you speak only one language, learn another one. Learn the language of your land, the indigenous language where you live. Learn the language of your ancestors, especially those languages that the state has tried to murder away. Learn an international language other than English, which have also been targets of state repression.
Prioritize languages that you both have some connection with (because it's hard to learn a language you don't care about) and languages that the state has tried to erase (because there are *reasons* those languages were targeted). Language (which can't be fully separated from culture) adds complexity. The state often tries to murder away language because (among other reasons) hierarchy is threatened by complexity. Every language adds some surveillance overhead, some more than others.
