When I am ill with an infection, I care not that "Not All Bacteria" cause the illness, I still take antibiotics all the same. If I have cancer, I do not give a shit that Not All Cancer Cells will destroy my organs, I still seek chemotherapy.
Capitalism is entirely a human invention, and the most widely adopted ideology. I care not that "capitalism is the problem" because if humans can't get their shit together, then they are the root cause of the problem and Capitalism is just another symptom.
Put another way, in the words of Jesus Christ (paraphrased): "Consider the lilies of the field, how they grow: they don't destroy their home and then pretend like they aren't the problem because 'Lily Capitalism is the actual problem'"
Oh, btw: Misanthropy != Fascism. Ecofascism is a belief that all people should stick to their racially segregated "homelands" and live in harmony with nature. Whatever people who say "'Humans are a virus' is literally ecofascist rhetoric" believe it to be may be the actual solution to the oncoming apocalypse we've gotten ourselves into. I'm a misanthrope who loves the biosphere more than humanity's right to do whatever it wants and get away with it because "it's the ideology, not the people who participate in the ideology." I'm not a fucking racist.
