I believe the preposterously stupid angle on this is "I've just heard of it, so it can't be a big deal."
And you knew it was racist ... when?
Stupid knee-jerk reactions to a statement that was learned from Saturday morning cartoons, as a funny thing said by a talking animal, cannot be understood as racist, nor meant as racist. To suggest otherwise is worse than useless: it makes you look stupid and petty.
I would suggest that the only people making this a "racist" issue are the ones who are pounding the table about it being racist.
I am certainly not going to accept your "racist" tag, because I am not a racist, and the statement isn't either. Sorry, but perhaps you should give your knee a rest.
