It's true that this word is unfairly used on a lot of white people.
HOWEVER, it is entirely wrong to say that black people are generally just as racist as white people.
Black people CAN NEVER BE AS RACIST. Unless they brutally enslave, torture and murder millions of white people. And that is never going to happen.
White people have a gruesome history of hundreds of years of murdering people. Black people .... Do not.
Therefore, many people are entirely justified in calling white people racist. Individually, definitely not. But as an entire race...well there are some pretty bad things to come to terms with.
P2: You are a fool.
PA: Black people are just as racist as white people.
PB: I don't recall black people starting a slave trade...do you?
All of this is funny because the white man is the one that is stereotyped as being racist, which is hypocrisy at its best. It's racist to assume that white men are racists.
If you don't get offended by racial insults, then you're apparently racist too, but an actual racist would get offended by it. When you hear a certain word too much (I'm sure we've all heard "cracka" hundreds of times thanks to standup comedy) then you become desensitized to it.
Well, that and the words white people get called sound stupid or non-offending. "cracker" came from cracking whips. Indiana Jones cracked whips too, and he was a badass. "honkey" sounds like some kind of gigantic sandwich, and "white boy" makes you seem like the lone white kid in breakdance movies that stands out amongst the other races and white kids. Most people only really think of rednecks when they think of "white trash" so they don't get offended by it if they're not rednecks.

"You fuckin' cracka ass racist! It's just because I'm black ain't it? You say that fuckin' word like you know what you be talkin' bout! You is ignorant!"
