re: this takes courage
"your friend" has interpreted your public post as a personal threat . It is now on record.
I'd say thats your first mistake. Your other mistake is posting the sort of material that would not be appreciated by certain people. "Your friend" has sent an email to you on an old addy, whether its still current or not only you would know.
I advise you to think clearly, and definitely not while under the influence, there are others who would suffer for your actions if you escalate this.
PS if the usual suspects are posting their comments, save your breath , youre already on ignore.
