Seriously, the idiots that think Jagex are being "fags".
If you specifically read what he said, it clearly states, "What a little Jew". If you heard that phrase, how on God's earth would you ever relate that to a penguin. Yes, it may have been taken out of context, but its a sorry sight to see so many sythe users simple abuse Jagex for muting someone that used derogatory language to a religious group.
They definitely have enough evidence to mute you. Yes, it may have been harsh, but then why refer to a penguin as a Jew?
