Redneck was originally a term for manual labourers from Ulster County, Ireland and it did indeed originally get its meaning from the labourers getting sunburnt fro toiling in the open air. Many of these people settled all over the Eastern and Southern US, but it only really seems to have stuck in the South, where they continued to be manual labourers in far greater heat and sun.
Over the centuries since, it's taken a new meaning: poor white trailer trash. Syill, people make a living out if it, like Jeff Foxworthy.
And yes, the Nazis spoiled the swastika for the Hindus, who had it for thousands of years. Now even the word seems evil-looking.
I'm sorry you felt the need to change your handle, '15, but people are sooo judgemental these days. Keep yer ears on, y'hea?
