If you're making music that can even obliquely be considered "protest music," I'd love to help you get it out there by mixing and mastering for cheap (or even free, depending on your financial circumstances).
Art made by conscientious people is very good for the world.
I've already mixed and mastered one protest song from a mutual here on fedi. :) Allow me to help, if you need. Send me a DM or find my email from my website.
