Since anarchy seen as our goal but also anarchists come to anarchy through prefiguration, i.e we have our means make up our ends, then we have anarchy as a means to anarchy, and so anarchy and anarchism are kinda the same things

And there are those of us who are not ends-oriented at all and treat living anarchy as a complete state, but I'm fine with calling that anarchism also

I don't care much about whether people are using the ism or not and I'm not sure it's more than just a semantic preference; for me it's more just about how well they do these things that destroy hierarchy
