Replying to I put "fried chicken in the whitehouse" as my status update on FB yesterday and got in huge trouble.

Now you have to understand that i am not being racist.  I was just poking a little fun and the culture that has grown amongst our African American brothers.  I have the GREATEST respect for President Obama, and I am incredibly excited about what is going on in our country;'s government.  This has been a long time in coming.
Anyone who knows me will understand that I was just making a harmless joke and it is IMPOSSIBLE to say that African Americans do not have their own culture in our country.
my question to you is:
Did i cross the line?
