Okay, within all of this, there is a phenomenon that truly stands out.
NOBODY ANSWERED OP'S QUESTION!
All you guys did is state your opinion on racism and OP's comments about arabs and europeans. His question pertained as to whether or not this was bannable, and all you guys did was yell "RACISM" in unison, like sheep... Yes yes, sheep don't yell "RACISM", they go "BAAAAAH!", but it's close enough!
Now, for the very first answer to OP's question: it's quite a gray zone. If someone interprets this as being racist and makes a good enough case of it, you could get the hammer coming at ya.
