This is so complex isn’t it. I do kind of see what your online friend was saying. So for instance you don’t need to be the person executing a crime to be guilty of it. Just being part of its planning, even being present and failing to prevent it can render you liable. Supporting a racist may not make someone a racist perse but certainly a racist sympathiser?
I get super riled when folk cite the economy as a reason to vote republican. For many reasons but mainly - it’s as if money is more important than women’s health a safety and women’s rights!
