I can see how what you said could be seen as racist. When you say "Who in their right mind would want to look like <insert any race here>" you are basiclly saying they are inferior. Perhaps this was not your intention but on the internet where we don't have the privelidge of knowing anything about you that is how it comes accross.
The simplest course of action would be for you to either edit or delete the comment.
I hope you can see why that statement looks racists. It is not a question really of if *you* are racists - the STATEMENT though clearly is. It descriminates soley based on race.
