(Serious question) Why are white people called crackers and the what's the origin of the 'H' word?

H onky is possibly descended from the following sequence: immigrants from eastern Europe were often called "bohunks" from Bohemian or Hungarian. 'Bohunk' evolved into 'hunky', and then 'hunky' started to mean any white-skinned individual [since obviously an eastern European person was pretty pale] and thus the pronunciation 'h onky' evolved from that. When I was a kid the racial epithets [e.g. negative terms] included 'k ike', 'yid', 'spick', 'guinea', 'wop' and the like...I think the world has improved a bit, since only the no-neck illiterate types nowadays ever use terms like that. Incidentally, the first use I can remember of 'cracker' was to denote someone from Florida, as in 'florida cracker'...kind of a trailer-trash redneck, only from Florida. White with a red neck [sunburned from ploughing midday] and a little tin house with 9 dogs under the porch. Capisch?
