"They have seen French and Brits also as not-aryans"

Not so simple, they also divided the german population by aryan and non aryan tried to "improve" by breeding programms (https://en.wikipedia.org/wiki/Lebensborn) and well hunting down all "inferior jews" and less so other people like sinti and roma.

And it is pretty established that Hitler wanted the UK as ally (who have been pretty racist at the time as well).

See also the flight of Rudolf Heß, which he did to make a favor to Hitler. (pretty interesting story, showing the delusion of the whole thing)
