i know for certain a couple of friends plus myself merely laughed at the "london sucks" tirade. "sucks" is an extremely american term (said by an english person it's actually quite funny) and coupled with his distinctive high pitched american accent i can say for sure pretty much that few english people were offended. the general consensus is pretty much that he's funny to watch on a tirade, he's an eccentric, and he's sort of the bad boy, maybe a john mcenroe of pool.
i just say this because i believe to often people seem overly offended at earl's antics. using terms like "disgusting behaviour" when really if you were going to say something "immature" or "silly" would be more accurate.
