The hypocrisy is the point. Jews, LGBTQ+, and PoC can be swayed to white supremacy if they believe they will be spared if they help the project enough. Of course, this is all nonsense. If the white supremacist project finally succeeded in exterminating all the "bad ones", they'd turn on the "good ones" next. When they run out of people to strip rights from, they'll start stripping rights from each other.
Edit: Changed "because" to "if" to avoid making a causal link.
