Sorry, but I don't think hga is merely "misguided."
He believes I should be forcibly deported to Israel and, if I refuse, should be killed. This isn't a belief that you argue with people about. We fought a world war against this belief.
You don't deal with neonazis by arguing with them. Whether Jews are equal humans or not should not be open to debate. You deal with neonazis by ignoring and/or banning them.
As much as I hate the doctrine of safe spaces, there's also the fact that I believe I should be able to come on Hacker News and expect to not have people calling for me to be murdered. Sorry if that's too much to ask.
