Verdis Elementum is pretty committed to fighting Sanguis Astroism.
Triunism is theologically moderate but politically radical. We've had prominent members call for extrajudicial violence against SA members before, as well as attempts at political persecution, and pretty explicit support for Averoth/Caerwyn in the current war. Triunism isn't totally radical like you seem to want, but it has its fair share.
More importantly, Triunism is still fairly small, and so a highly involved radical could have significant influence to change Triunism.
Verdis Elementum's official stance is "ignore" for every religion. And it will remain that way until a faith starts using persecution options against it. Verdis Elementum spreads beyond Caerwyn and the realms openly hostile to SA.
VE is mostly about enlightenment of the self via study of the elements, so not really what the OP is looking for.
