I didn't give impracticality as an excuse. I just don't agree with ethnic cleansing. Everyone has a right to live where they were born. Furthermore, it just doesn't track with the indigenous people I actually know in real life. I can't imagine any of them wanting to expel most of their friends.

do something more meaningful

I help with language revitalization on occasion, there are places coders like myself can help there. I'll admit it's not exactly a full-time job, but it has its value. But in general I don't want to bother people who live on reserves. Regardless, I reject the notion that you need to actually be helping in order to have an opinion.
