You are inventing that anyone is condoning killing innocent's BUT that's not even important.
You get to pick, you want more deaths, less deaths, or don't care.
There are no other impacts you can have with your vote.
If you care deeply you can join marches and protest. The many people who are doing so will gladly tell you Harris is not doing enough, but that it would be idiotic to not vote for her.
Arnold absolutely sucks for what he did, I have long pointed to it as one example of why he shouldn't be so glorified for not being completely insane as other Republicans.
That said, the other poster you're talking to is in the right here, you're ignoring the point entirely.
