adding “arts” to STEM is akin to “but all lives matter”

It most certainly is not.

but that’s not what we’re talking about

I’m talking about a particular genre or theme I made up out of a word play. What are you talking about? And, more importantly, how including Arts with STEM is on the level of white supremacist dog whistles?

You’re free to make STEMpunk a thing if you want. That would be fun, ironically that would be slightly on line with creating ‘all lives matter’ to oppose BLM.
