You just can't seem to choose whether it's OK to quantify harm and advocate for harm reduction on that basis or whether harm is qualitative and cannot be reduced to simple numerical comparison.
Which is it: it's disgusting to the tell the victims of sexual violence under Obama and Biden that Trump is presiding over more of it and that's why it's OK to vote for Ds, or it's virtuous to vote lesser evil and harm reduction on a quantitative basis?
Did Biden prosecute the perpetrators of sexual violence against detained immigrants? Did he address the harm? Or did he ignore the harm?
It sounds to me like you are deeply attached to the idea that Democrats are NOT actively participating in the system and that the Republicans are. To me, the evidence is clear that this is a Good Cop / Bad Cop situation and they both work for the same department and you're just being duped by the routine.
