You're assuming that the basis for their hate is rationality. If they were rational people, they wouldn't be racists/fascists/hate groups/etc. Assuming you're correct that having "some success" removed people from such a path, it's still just drops in a bucket. Recycling the contents of a dumpster won't stop climate change.

This might shock you but speaking as a person that has rationally argued with racists, they have plenty of empirical data to back them up and they believe their position is rational. That does not mean it isn’t an arguable position, such as criticizing their data as being cherry-picked.
