No, radicalism can be used in any culture, why are we going to persecute one culture when other cultures have people that do it?
If we want to defeat radicalism in all it forms, we need to talk about it from all angles. That means we need to talk about religious, gender, racial and sex radicalism as well.
Don't do things half full and then complain that you see no change, do it full and be happy that such a thing can be eradicated.
