I think that's because we have a difference of perspective on degrees of bad. I think all deaths caused by capitalism are bad, and equal bad to all the deaths that are the result of authoritarian countries calling themselves communist.
So i fundamentally disagree with the "relative to what" because a life is worth the same regardless of where they live and who they are.
We are able to, and I am talking about the harm, and I am pointing out that this meme is designed to create an emotional response to the 2nd point and not to both points. Thats all, its manipulative and propagandist which makes it in bad faith, and you are welcome to defend either position, I will just disagree.
