This keeps coming up. So a quick word about radicalism.
“Radical” does not mean violent, bad, extreme, or “too much”. It means, literally, striking at the root.
A radical leftist thinks you cannot improve our political institutions, you have to replace them. A radical feminist believes that you cannot simply pass a few laws to give women equal rights, you need to transform the whole of a sexist society. A radical fundamentalist Christian believes that Christianity must be understood as reading the whole text of the Bible literally. One can advocate radical change in teaching curriculum for math or manufacturing methods for automobiles or programming languages for computers or women's fashion for the next season.
I use the word “radical” descriptively, not as dismissal or an insult. Many things need a radical approach.
