I have attached the relevant irc log stub. It's simple:
1. Person breaks rules.
2. Moderator warns that person.
3. Other person continues the rule break.
4. Moderator punishes other person.
5. Other person complains.
Iran was warned (more like the entire server was), and you were muted because you continued (and enabled) the racist discussion. Normally I would feel inclined to be lenient, but I spent the past 45 minutes scrounging through a large irc channel's log file to look for what you were referring to while you could have lead your complaint with it by posting your own log (you're in irc, after all and told me you have logs).
So I'll have dblaney decide if he wants to unmute you. It's also his server, so even if I wanted to be lenient I'd still go through him.
I see no reason to unlock the thread at this time. If further discussion seems needed, other moderators have permissions to do so.
