I didn't find the slides so bad. But..
> Ally is a verb, not an identity
That's... that's a noun.
> Ally is a verb, not an identity
That's... that's a noun.
Those slides present a rather extreme ideology, which is not based on (and is often flatly contradicted by) evidence.
Western society has a long history of producing ideologies centered on guilt and sexual propriety, and intersectionality is just the latest iteration. It's a descendant of puritanism.
> Ally is a verb, not an identity
> [...]
> Acting as an ally is about action - it is not an identity, which is why we talk about "ally skills" instead of "allies"
(In military slang 'ally skills' could be adjectival use, but I'm pretty sure this is using it like 'friend skills', a noun.)
I take the following sentences as confirming this reading:
> Being a marginalized person takes no action - it is an identity:
> Acting as an ally is about action - it is not an identity, which is why we talk about "ally skills" instead of "allies"
> Depending on what is most relevant about you to the situation, you may switch between being marginalized and acting as an ally
