Uh, yeah, it's racist.  Use common sense.  Stop acting like you don't know the difference.  Sure it's pretty easy to say something like that over the internet.  I don't even know you, but I'm pretty sure you wouldn't say that to a black person's face.

There is no "rule book" on racism.  No neat nice little checklist of what's okay to say and what isn't.  Just use common sense and you should be fine.

Yea well there is my problem common sense.  To me it is just body parts (is it mature to joke about people's looks no but sometimes it is just easy cheap laughs).  It has just got to the point where it is allowed if the person is Jewish to talk bad about themselves but no one else can make light fun of them or they might be a racist.  Same applies to apparently almost all races.  People get up in flames if somehow another race talked bad about them but then laugh if it is the same race.   Just seems stupid to me.  I just view all people in a negative manner until they can surpise me and make me realize they are a decent human being.  I don't care what race a person is.  There are good people and shitty people in all races.

Oh and by the way I did say that to a black person's face.  It was about 17 years back in high school days in a class clown battle.  I was usually the reigning clown but had competition in a class and I believe he started joking about my false tooth (has little metal bits that stick up a little on sides) so naturally I went low and inquired about his nose.  I also won't refer to them as African American because I wouldn't expect someone to refer to me as a English Norwegian German American.  I'm a decently big guy at 6'2" and can get along or fake get along with anyone.  So usually I'm friendly and just joking around but some things I say can be very questionable.  Sometimes I just like flirting with the edge.
