Every single truly reformed reactionary I ever met in my ENTIRE life, and they're rare, but they do exist, has a version of their history that starts with "and then one day I looked around and realized everyone I cared about had left me and the only people still willing to tolerate my bullshit were a bunch of nazis."
For the same reason you don't debate nazis, you don't try to hug them out of fascism and fascist ideology. It doesn't work, it just validates their behavior. Walk away.
