There are many dumb people and assholes on Wikipedia, as in real life. Also as in real life, there's no way to force any of them into an apology. People expect more here because there's a policy called "civility" but that actually doesn't guarantee any restitution. As you've been advised before, it would be best to accept that and let it go. If Jimbo answers you, chances are it won't be what you want to hear.
