What do you think about this example of racism? Is it racism?

On the show Big Brother one of the girls on the show has been accused by other Big Brother Members and the public at large of being racist based on some things she has said.

Most recently they were all together and Aaryn, the one accused of saying racist things, said a sentenced and used “aksed” and then corrected herself to “asked” (purely accidental in my opinion just from icking it up in the house) and turned to the black girl and said, “now you have me saying it.” The black girl, Candice gave her a look and so did some other house members. Candice said into the camera later in private kind of defensively and with attitude that “it’s a dialect, ...” The black girl has been very upset on many occassions by what Aaryn has done and said regarding race. Candice is very well spoken in general, she is a speech therapist of all things.

Now switch to another girl in the house, Gina Marie, she is blond (not naturally) and Italian-American. Her accent is pretty badabing, her vocabulary isn’t great, and she pronounces words wrong all the time a la President Bush-esque. When she knows she is tripping up a word she will struggle to say it, sometimes laugh at herself. Now and then people correct her, and she says something like, “wait, what, what is it, what did I say?” And then attempts to say it again. Everyone laughs as she struggles including her.

Is there really any difference between someone making fun of Gina Marie’s accent and mispronounciation, and observing the mispronounciation Candice uses sometimes?
