It’s not about the asana being “right” or “wrong”, and in many cases I’d say it doesn’t even matter what the asanas are in your practice, as long as they’re moving the practitioner towards dhyana. But would you not admit that there is a lot of cultural appropriation around yoga in the west? Girls on Instagram with “Namaslay” shirts and dream catchers and sanskrit tattoos? Taking, packaging, marketing, and selling things in this way is racist.

Of course the modern practice of asana in the west isn’t inherently racist, and you don’t need to only be doing postures that were written down in old books. But wearing an Aum shirt and never understanding the deeper cultural contexts of what it is you’re wearing and practicing is racist. I’ve had conversations with people that have practiced yoga for years and literally have asked me “what’s asana?” and had never heard of pranayama. Were they racist? No, probably not, but it does speak volumes to how yoga is sold in the USA.

I don't think you should be using the word "racist" here. Seems people are culturally disinterested but "racist" is something else.
