As I understood it, "radicalization" was a political science term that generally referred to people who had been pushed too far and, as a result, were ripe for political mobilization. So people like former peasants pushed into factory jobs relatively far away from their home villages or former housewives pushed/lured into the labor force or former factory workers in america or hippies who found out "free love" wasn't free, ect were often quite discontent with the state of things and often felt disconnected from things around them. They often experienced a strong sense of alienation from their surroundings. Hence, they were often bitter and angry, as well as lacking a desire to preserve the community around themselves, even perhaps wanting to destroy it/make some major changes to it. So, those kind of people were much more likely than others to respond to a revolutionary/reactionary (counter-revolutionary) message.
Most people tend to want to "conserve" the community around themselves and the way it is organized. Hence the term, "conservative" and the reality that most people are in fact "conservative." Iirc, they are what Nixon called "the silent majority."
Therefore, trads should fall into the category of "reactionaries/counter-revolutionaries." They or their parents should also have some history of radicalization. Not surprisingly, trad chapels often seem like hotbeds of counter-revolutionary fervor and "paleo-conservativism." Of course, that makes them targets for revolutionaries and "conservatives/neo-cons."
