I think SSPX probably harbors a lot of the same views, but they're established enough to at least put on a veneer of being compassionate, especially when compared to the flood of smug and openly hateful zoomers rotating through various podcasts. I don't know that they actually are much more moderate, but they are less blatant from what I've unfortunately come across.
It's concerning that the conservative Catholic content which is pushed to anyone taking even a minor interest in Catholicism makes SSPX look relatively moderate.
Some, like the ivy aphid are already in North America, but I'm not sure how much of a dent it actually makes. There's great precedent for successful introduction of biocontrol agents for other invasive species. There's also great precedent for catastrophic failures(especially in instances where there's a native close relative of a target species), so it's definitely something that needs to be very carefully explored and not to be done haphazardly.
Still very evil however. They're still kicking up dust with 4x4s and doing ecocide just for kicks.
