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. One can advocate radical change in teaching curriculum for math or manufacturing methods for automobiles or programming languages for computes 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.
