There is no number of foreigners that is unacceptable to sacrifice for a middle class livelihood. Anti-cop because they can imagine a scenario where a cop inconveniences them. These principles don't apply to the Waffen SS because they can't imagine a soldier personally inconveniencing them and, of course, foreigners aren't really humans.
You can't hold them accountable if you have no power.
We can start holding them accountable by not letting them think they're absolved. Your comment isn't even willing to do that
How is this holding them accountable if they are free to continue doing their shit?
If all you can do now is push back when you hear someone downplay their service, that's still better than letting it go
I think that "letting go" should only be an option for people who are genuinely switched sides to the revolution. But you wouldn't have much success to switching them without even showing them that this option even exists.
