His film do have repeated anticapitalist and antifascist themes. I don’t want to label Miyazaki, because I will get it wrong, but I have noticed similarities between those themes and William Morris’s utopian socialism.
A lot of Communalists also like the left, feminist, ecological and anticapitalist messages in his films, so if he isn’t that left then people who are very left and usually well read are reading too much into his work. I don’t know if Murray Bookchin ever watched his films though.
