Bashing people who are on your side cuz they aren't doing enough or aren't doing it right, I spoze that's a route to change. Might not be a route to the change you want, tho.
If bashing people is your thing, tho, why not consider aiming at the people who *aren't* on your side?
Or, of course, if you wanna go *deep* radical, try love. It's harder than bashing, but the rewards are better, and you don't have to worry about the route.
