Effectively to create an outcast faction that tries to get rid of cardamine is difficult and nearly impossible.
As I know there are are just a handful of people such as Lee del Sol Verde, who have managed to clean theirs organism from cardamine. He even got help of Cryer for this prodecure, but the result has marked him, has nearly killed and has made him completely mental-ill.
Creating a group, with taking this as a reference, is in my opinion unrealistic, because to much people will simply die to the procedure or will be to much mentally destabilized to form actively a group of influence in a later state.
