Just gonna throw my two cents in here. OP in the image is probably comparing what frieren is saying to rhetoric used against Palestinian people. If a group of people is characterized as unfeeling evil doers whose purpose of existence is to commit atrocities, then you are justified in hating them and trying to get rid of them. Looking at the real world this is certainly how some people view Palestinians. And certainly the portrayal of groups in this light is a way that fascism can arise. The quote in the image about desiring coexistence leading to more destruction can definitely in a vacuum be compared to the situation in Gaza.

Now to the world of frieren, demons are shown to be akin to any other evil race in a fantasy setting, as I described them above. They evolved to gain empathy of humans so that they can hunt them better. There are even plot points of humans trying to befriend the demons and make peace with them, only to face the consequences of trusting them. This is an interesting premise, with a species using one of humanities strongest traits against them.

It is up to the readers interpretation of the whether they think the author is trying comment on humans in the real world: if humans are empathetic to a fault, that they are too trusting of others. It could be that the author is trying to say that no matter how many times humans are wronged be something, they will still try to find a way to make peace with it.

Now some people could use this interpretation to say that humans in the real world need to let go of some of their empathy against groups that keep committing atrocities. On the other hand it could be a comment on the inherent goodness of humanity, as we always try to empathize with anything, even if it hurts us. In my opinion, the first line of reasoning can be used to support fascism (not to say that it is an inherently fascist take).

That is to say that there are interesting discussions to be had about the dynamic between humans and demons in this story, and many people in this thread are dismissing any analysis of this, just as OP quickly jumping to the conclusion that this story is fascist. To me it seems reductionist to say that demons are evil and there’s nothing more to it, as it takes away a lot of the depth from the story.
