How did I not know that until now?
Unironically, I'd like to know. Not having a go at you. There seem to be lots of people who don't know that. But without that bit of knowledge, the holocaust doesn't make sense.
The nazis defined anyone with jewish grandparents to be part of a jewish race, by law. That even included a few christian priests. Of course, the nazis didn't invent the idea. People never liked converts much. When you prosecute someone, you want to get the loot. It's never about selflessly helping people go to heaven.
Historically, it's a truism that a race is a result of racism. First, a group is hated or subjugated. Then membership - and supposed negative traits - become defined as unalterable, heritable facts.
Huh. What a weird coincidence. Out of all the many communities in Canada, it just happens to be the indigenous ones that have to make do without clean water because of military spending. What are the odds?
