[I haven't repeated this disclaimer recently enough. "Race" is a sociological construct with no biological meaning.]
1) Apartheid South Africa gave special status to Japanese people - honorary whites. This doesn't mean that the Japanese people could control their own status; it was a special status given to them by the white supremacists who wanted Japanese trade deals.
Similarly, your 1) is for people were granted special privileges by the racist Christian Germans because of the services rendered for the racist power structure.
But the racist power originated from those Christian Germans, not Jewish Germans.
So, great, you've discovered that some black slaves avoided whippings by helping their white slave masters keep the other slaves in line. With as much sarcasm as I can muster: If only those black slaves hadn't been so racist.
2) How is this racism, any more than white gangsters killing white people? So if a black business owner shortchanges a black customer, that's also racism?
3) Are you effing kidding me?
Everyone who is outraged at, angry with, or otherwise against the police violence against black people is an SJW.
I am an SJW. 60% of Americans believe that ’Racism is built into American society. The assumption of white superiority pervades schools, business, housing, and government.’ according to a recent Yahoo News/YouGov poll. 52% agree that "President Trump is a racist." The majority of Americans are SJWs.
If you are not outraged .. why not?
Drop the nonsensical "SJW" rhetorical label. Demand social justice and equality.
Now, back to 3) By "example" I don't mean some abstract story. Because I remember the lying stories Republicans used about black welfare queens in order to harness good old American racism to shrink our social safety net.
"Agents"? How sinister! You know you could have left it as "SJWs", right?
Your terms have been so over-used by right-wing extremists that they have acquired new meanings.
Your "more discrimination" comes across like those people who insist that "feminism" means not "gender equality in the public sphere" but wrongly that "women should be in charge, and men should be hated."
While your "cancelling" bring to mind all those people who think "cancel culture" means "no one expressing bigoted ideas should ever have to face consequences."
