Logician: Why is that problematic? Saying it’s evil to kill animals might be bad. Saying that we kill too many to satisfy our own Taivas doesn’t feel like a problematic Hashkafa. I don’t know if it’s true or not but it feels like just trying to become a person with more Rachamim and sensitivity. I don’t see how that can be a bad Hashkafa.
By your logic, any Chumra is a bad Hashkafa. That’s ridiculous. We’re Machmir not like Chazal all the time. Why should this be any different?
