You start with this:
>I truly don’t understand what the hope to gain from self-classifying this is “feminist”.
To which I say - why not? Is this the problem?
Because it creates weird, presumably unintentional implications. One such implication:
> They seem to imply that feminist = artistically produced, as opposed to professionally produced PCBs. So masculine = professional? But clearly that wasn’t their intention?
That a feminist art project or collective has to be defined in opposition to something else is entirely your own framing.
This is where your mind goes when you read “feminist,” which reveals your priors.
